I had two ideas for why to fill up the stomach with air:
An extra supply. I bet that if you practice it you could mix the stomach air and the lung air while underwater.
or, perhaps there is some (small) O2 absorption in the stomach lining or small intestine. If you could push it in there . . .
Both options require remarkable and somewhat disgusting control of one's internal muscles. But if anyone could do it, this guy looks like he could.
