Blarge Question And NFHS Response

Would this play require anything different in the ruling or approach?

From C’s primary A1 drives along the baseline and he jumps and releases the ball on a try. Contact occurs between A1 and B1 after the release and before airborne shooter A1 returns one foot to the floor. The C signals a charge based on his view that B1 had established legal guarding position. The L, who is still on the other side of the lane, signals a block. His view included B1’s foot being placed on the out of bounds line as B1 attempted to establish legal guarding position and remaining there when contact was made.
