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.
