You don't know if he's doing it right. And snapping your tail on a straight air is jumping 101. Unless you are watching too many snowboard addiction videos.
If you simply ride off a jump with a little hop at the lip that doesn't mean you are going to get any pop out of your tail. If you never learn to do that via timing and board control you will never have a straight air with any boost.
