Can someone explain (sorry, very basic question)

I see a lot of trading of TE and WB etc then an opposite side back going in motion almost immediately. Also the guard signally the snap by slapping the center technically violates the rule I posted. I also see lineman with their hand down squatting and looking to the sideline for play change, spirit of the rule says once the hand is down, stop moving.



c. Any A player on his line between the snapper and the player on the end of his line, after having placed a hand(s) on or near the ground, moves his hand(s) or makes any quick movement.
