Yes he rotates all the way through, have a look at the way his arm snaps with his punches, there's no push. I think you and others have a bit of a misconception about what a snapping punch is. You know it's a snapping punch when the arm is still accelerating at the point of impact, a pushing punch isn't accelerating because the tendon isn't recoiling into the punch. A pushing punch is all muscle, a snapping punch is tendon. Tendons are responsible for power, muscles for force.
When you jump into the air you put a lot more force into the ground than if you're standing there lifting the heaviest weight on your back that you can.
You're applying far less force with your muscles during the jump but the resultant force into the ground is far higher due to the recoil of the tendon. It's the same principle with a snapping punch.
