Not sure what your first sentence has to do with what we are talking about.
If I understand you correctly, you are suggesting that Djokovic has a 1-2 Punch (FH + BH) which is the main reason why you think he dominates Nadal.
If that is what you believe, I disagree with you. At the elite level, the quality of the stroke is irrelevant. The important things are shot selection, and making the ball.
Djokovic has always had superior shot selection and more consistent ability to make balls on both sides of his body. So FH+BH, BH+FH,etc. doesn't matter in his case.
