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?
IMHO, the coach is correct.

Don't get caught up in descriptions like this. Nobody can accurately reproduce any of this stuff on demand. The physics are too precise and fast. It has to come through the brain's learning through trial and error. In general, hitting a straight shot baseline-to-baseline requires primarily hitting the the back of the ball.

I'm not a coach, but I'd probably tell someone something very similar.
