Yes, but Vegas has the elbow as close to his hip as he can @ impact. So this is not an "upper body TSP motion" on the EP.

A note about Tiger: He moves his neck down and up again, but he keeps his hips more level than most throughout the swing. The alternative is to keep the neck level and move the hips up and down and up.

When you think about where the swing center is (where the sweet spot plane meets the torso), it may not as bobby as by first sight to move the head and keep the hips level.
