I get that what he's trying to do is decrease the rate of closure between the main gear and the runway at the last second by rotating the plane.... But isn't that going to be negated by the fact that pitching down increases your rate of descent for the airplane as a whole. The energy of the aircraft sinking has to go somewhere... Traditionally that downward motion is stopped by the flare.

Maybe this works for Eric here, the youngest G-280 pilot in the world according to his bio. I would rather my pilot just follow the checklist set out by experienced company test pilots working with multimillion dollar budgets alongside the engineers who designed the systems.
