Time of Pitch

[Illini_Ref]

I'm not trying to split hairs here, I am just having a hard time unerstanding a rule. NFHS rules.

Pitcher in the windup. Glove hand is in front of his body and the other hand is at his side. He deeps the hands there and steps back with his non pivot foot. He thens stops all together. Infraction or not.

NFHS rules say that the TOP in this situation is any movement with the arm(s) or leg(s) AFTER bringing the hands together. Am I reading this right? If I am then there is no infraction, as he is not committed to the plate until there is movement AFTER his hands are brought together.
