I know that the Patty police say you must show little bubbles when the regulator is out of your mouth. Of course there are no lung damaging pressure changes that are affected by having a regulator in (or out of your mouth) so the whole idea seems more like a reminder and a good idea - rather than a danger.
However, people are worried about that, but don't seem to be worried about a guy demonstrating the inhalation of high flow rate air at 3000 psi ( (i.e., breathing right from the tank valve). Seriously, that has to be a lot bigger issue if you accidentally seal your lips on it. That skill is a lot easier to get wrong then swimming horizontally while holding your breath.
