balk??

[spots101]

This one has me a little confused. The pitcher, while in the set position, starts his preliminary movement to bring his hands together in front of his body for the required 1 second pause. Typically, most pitchers make that "circle" with both hands where the ball and glove meet at their face/chin but not always. Anyway, while in this motion can the pitcher immediately turn and throw to first base before the hands and glove come together?
