No different than if I tied some latex surgical tubing to the end of the cylinder rod, which would retract it if air pressure was released.
However,
your point about safety is an excellent one: A gentle movement to a safe position with air release is one thing, but I can imagine some violent stuff that can happen when air is released (or lost) which could be quite dangerous and must be avoided.
