Although I am very big on the whip analogy in serving and have talked about it on these boards, your drawing and the serve motion are probably closer to multiple catapults. Force is applied at each catapult in the system and the best result is when the forces are timed correctly. (Not like a whip where force is applied only at the base) Since the wrist has comparatively little force imparted to it and is so flexible, it may act more whip-like than the other joints.
