Because you can knock a door with your hand down as well and it would be more convenient?

leverage/physiology … **try throwing a ball any other way.**

even underhand you need a bigger swing to get the same distance on the ball (assuming similar release heights)

You can throw a ball (or knock harder/easier) with your arm in that position
