I discussed it with him later and told him that I didn't feel it was possible for the ball to hit the back of the board and go straight down.

I disagree. Short if some incredible spin on the ball, only the rear surface of the board can apply a force to the ball that stops its forward movement. The bottom of the board can only direct the ball downward....it doesn't affect its forward movement. Likewise for the back...it doesn't deflect the ball downward, only back towards the OOB area.

So, if it hits the board and deflects directly downward (all forward momentum lost), it hit both the back and the bottom. If it continues to the front of the backboard, it hit only the bottom.
