I Thought it was funny, yet wondering if it would actually work at the same time lol.

it can work if it is air in the bag and he is exhaling through his nose similar to what one has to do to clear their dive mask. though if he was inhaling in from the bag, the bag will contract similar to a balloon, so I do not think he is inhaling from the bag.
