Why not likely?
What if one of the pilots is in the bathroom during a decompression and the other pilot in the flight deck is unable to don the oxygen mask (technical issue with the system, startle effect, reduced visibility, noise, panic, ...), but he is able to turn and pull the altitude selector to start the decent just before he passes out?
A random altitude, below minimum grid altitude, has been set and there is no conscious person in the flight deck to adjust the altitude to a safe altitude.
The pilot in the bathroom has donned his oxygen mask, and waits until the aircraft levels off and a PA from his colleague in the flight deck is made that the aircraft is at a safe altitude to breathe, since he doesn't have portable oxygen to leave the bathroom.
He would never expect that the aircraft will never level off and that his colleague is incapacitated.
