IMHO, at most it's a trope, not a clear indicator of AI generation. In my novel Falling Up I used this behaviour, not those words, more than once. It is a known behaviour in certain circumstances. Some examples from the novel:
—
Sam didn't cry out this time as they passed over the peak. He knew what to expect, and it gave him a thrill. He let his breath out in a whoosh when he realized he had been holding it.
—
Then he formed the walls and roof, but added two pipes above them, one directly above the burning torch in Lucy's hand. They could feel air moving past the torch and up the pipe. A smell like frying bacon filled the air, making Peter's mouth water. Then he lowered them into the water.

Lucy reflexively took a deep breath and held it, then about the time it was up to their knees but clearly held back by the shield, she exhaled with a little self-conscious laugh.
—
The children were just standing there, looking at him expectantly. After a second, he crouched down, motioning for them to crouch as well, and holding his arms out to his sides. This would be a stretch! So many children at once, and he'd better not let even one fall! He concentrated all around him, fixing in his awareness where each one was. Then, when they were all crouching with their arms out just like him, he swept his arms down and up, then jumped! All the children copied him, and instead of a small jump, they soared into the air, paused motionless at the top, then gently returned to the sand. The children were screaming in joy, waving their arms around, and several were trying to jump like that again on their own.

He crouched down again with his arms out to the side, and though the sound of their joy reduced, it didn't go away until they were all crouched once more. Then they seemed to all take a deep breath and hold it, waiting for the jump. They shrieked as he took them just a little higher before bringing them back to the sand.
—
Emilio gasped at the sensation of falling, then started breathing quickly when he and Peter rose off the floor a few centimeters.
—
Martina Ramirez stood beside Peter on the path, pensively watching the children playing inside the zero-G playground Peter had just created. She had to speak loudly and distinctly to be heard over the shrieks and shouts of the children. “I know I gave permission for this, but it looks very dangerous. Are you sure the children will be safe?”

“Gabriel and the other children have one of these on their island, and so far, nothing serious has happened there. I agree, though, accidents can happen, and on this kind of playground, perhaps are more likely. Could I suggest that you ask staff to take breaks here, possibly with a bandage or two in hand?”

Martina gasped and held her breath as a child tumbled down the stairs onto the grass, then let it out when the child immediately jumped up and ran back up the stairs, hooting, apparently unharmed.

“Well, it seems my fears are somewhat unfounded.”
—
Martina was not expecting that a 'quick flight' would entail flying straight up several stories and over the building, then down to the pavement by the emergency entrance. She held her breath for the whole minute or so the trip took. When gravity returned, and she was standing again, she was red-faced and started breathing heavily.

Peter asked, “Are you all right?”

She managed to gasp out, “Yes! Oh, yes, I am fine! So thrilling!”

Peter nodded, grinning. “See you again soon.” With that, he and the other men flew off.

Martina was still walking a little unsteadily when she passed through the doors into the hospital. It appeared no one had seen her arrive, and the receptionist looked up with mild interest as she slowly walked by on the way to her office. For the receptionist, this was just an ordinary day.
—
Peter sensed Gabriel nearing the door in the hallway, and he turned just in time to see Gabriel burst back into the room. “The doctor allows you to make me fly here, but warns there should be no ac-ro-bat-ics.” Lucy translated, and with a slight grin, faithfully pronounced the big word at the end the way Gabriel had.

Grinning back, Peter replied, “Well, then, let's not waste any time.”

Gabriel raised the arm that wasn't in a sling, staring at Peter in expectation. He felt the weightlessness growing inside him. He turned his face upwards, drew in a deep breath, then closed his eyes. Peter held him there a few seconds, saw him breathing deeply, then raised him off the floor.
—
The man tensed as Peter built a gravity field inside him, and Peter waited for him to get used to it enough to not move during the turn. It was at least a minute before the man started relaxing. Then his gasps changed to deep, relaxing breaths. “Thank you, thank you, this is so wonderful!”

The doctors looked both surprised and confused because so far, they hadn't seen anything happen, the man hadn't moved.
—
Martina had understood Peter could travel long distances, but it hadn't really sunk in before. The shock of it made her feel faint. She stared at Peter. “Wait, do I have this right? You had breakfast in Puerto La Cruz this morning, flew to Maine to get Lucy, went back to Puerto La Cruz and picked up Carmen, then flew all of you in the van here to Bogotá before lunch?”

Peter nodded and opened his mouth to answer, but she wasn't finished yet.

Her arms — and her voice — started to rise as she continued. “And now you're going to do that whole trip again, soon enough to get Lucy home before her parents start to get worried about you bringing her home too late this evening?”

Peter, not realizing Martina's mental state, replied, “I don't think this will be a record for me. After all, we did a fair amount of travel recently where we and the Colombian military took out all the drug plantations along the coast of Venezuela in one day. Carrying more, too. Tanks, armoured vehicles, buses, troop carriers full of soldiers...” His voice trailed off as he noticed Martina standing, unmoving, eyes wide and arms still raised.

The silence seemed to break her out of her stupor. She dropped her arms to her sides and sighed, “I need to sit.” She stumbled as she turned, and would have fallen if Peter hadn't caught her.

He set her down in a chair, and watched as she limply put her elbows on the desk and her head in her hands. He wasn't sure if she even noticed she had flown there.
Then he turned to see if Carmen was ok. She seemed to be, though she was standing there unmoving, except for blinking rapidly.

Then he looked at Lucy, who closed her mouth, turned from staring at Martina, and looked back at him calmly. Then she smiled. “I guess she's not that used to taking trips with you yet.”

Peter realized he had been holding his breath and started breathing again. “This was only the second time she's been flying.”
