Facial immersion has been recommended yes, but face down on the surface before a dive, not while you are just about to die underwater from a BO.
Kirk and Mandy teach it in their courses and it relaxes you, assisting your mam. reflex to kick in. Laboratory conditions are always theoretical, Sean ascending from a dive, possibly a deep dive, on the verge of blacking out and then removing his mask is possibly going to relieve him of his DB membership
