I took that to mean the racket face has to be perpendicular to the sideline which means the swing path naturally is parallel to the sideline.

But, this does not make sense if you believe the rule that the angle of incidence=angle of reflection. In other words, the racket face and the swing path would vary depending on the angle of the cross court shot, the more angled the cross court shot, the more your racket has to face towards the center of the court if you are trying to hit a DTL shot.

What am I missing here? Was the coach wrong in telling my son to aim at the back of the ball or does the force of the swing change the rule of angle of incidence=angle of reflection?

You have to compensate for it. Even at the pro level, you can see DTL misses (ball not entering the court) when an angled CC ball is being hit DTL. The more the ball is moving and spinning away from you, the harder it is to pull it back into the court. The heavier your racket and the faster the swing speed you have, the less necessary it will be to make a CC-pointing angle with your frame.
