I'm sure the air bags run when the car is on and the doors shut.

Actually air bags will stay on after the truck is off to keep it level(if there is a slow leak). And the issue on a lift is that while the truck is raised the height sensor sees the truck being at max height so it releases the air from the bags trying to lower the ride height. So when you let the truck all the way down off the lift, with no air in the bags, there is always the possibility of damaging the air bags.
