Just adding to this excellent comment:
When learning to dive in a dry suit, there is specific training in what to do if you get inverted, with all the air going to your feet, because the valve to let air out of the suit is on one of your wrists, and won’t work if the air is in your booties: basically tuck and rotate with giant balloons at your feet.
It could be a real problem - there is 1 atmosphere of pressure difference per 33 ft of depth. An uncontrolled ascent is very bad in diving.
