Balk?

High Scool Varsity game. Right Handed pitcher takes sign from catcher with right foot on the rubber, left foot in front of the rubber, and right arm dangling down in front of his body as he leans forward. While still taking the signs, he brings his right hand up and puts it behind his back, still leaning forward. Is this a balk or not?
Thanks in advance.

From the 2005 Fed Interpretations - SITUATION 5: While in the set position, F1 has his pitching hand down in front of his body, swinging slowly as he gets the sign from the catcher. RULING: The use of this “gorilla” stance in the set position is illegal. A pitcher, for the set position, shall have his pitching hand down at his side or behind his back. (6-1-3)
