I originally had the same thought about the QD coming undone at depth. So, I TRIED to do it in my living room. You can't. If you look closely at the connection lugs, they are built so pressure increases the effort needed to disconnect it. To disconnect I have to bleed the reg all the way- and I mean ALL THE WAY- down. No leaks or orther problems that I see. I would think it is as likely/unlikely a failure point as a swivel mount to a console or the fitting at the first stage.
