The stringers I talked to also noticed it. The near-edges are filled with fuzz and worn out when advanced players bring their racket.
I am sure if you watch a pro hitting many balls in super slow-motion, you'll pick it up: unless he hits flat, he'll almost always make a low contact.
With that said, you shouldn't be thinking about this. If anything, it will become an habit by trial and error, through practice and time. There are other details that are more important, I would say.
