I do have a problem with that technique: you should not have your snorkel in the mouth when you dive. Whenever you dive, you must remove the snorkel. Simple safety Rule from Freediving.
Not sure if you were serious or joking. This is for snorkeling. The technique is foolproof with a little practice. When snorkeling you are not supposed to remove the snorkel from your mouth. Free divers don't use snorkels. I suppose the scuba divers that do use a snorkel could use the technique if they put the snorkel in their mouth prior to surfacing, but I have never heard of anyone doing that. Thanks for watching.
