anything wrong with this pitching sequence?

[Tex]

Was taught how the pitcher is to step onto the plate and simulate taking the signal at ASA national umpire school.

If the pitcher steps onto the pitching plate with hands separated and immediately brings hands together all in the same motion, that an illegal pitch is to be called.

Must be 2 separate motions separated by a pause (step - pause - bring hands together). If all in the same motion, the simulating of taking the signal with the hands separated cannot take place during the pause.
