In one of the videos, after the fin comes off the 321 it appears there is a fuel leak from the rear of the aircraft, I would assume the APU would be running at this time, unless it’s US.
A friend of mine years ago got hit in a freighter by the high loader not stopping, this knocked him out the seat, hitting his head on the side window.
Any reports of cabin crew injuries, they’d be up and walking around at this stage, interesting if there had been a fire and an evacuation.
