There is seeing something, then there is what the minds eye does with that imagine.
Everyone can see the same thing, but how it's processed, seen by the minds eye, that is something only that person can "see".
One reason I like to "see where the CB needs to be" v trying to hit some points on two balls that can not be seen, is seeing where the CB needs to be doesn't change with where my head is or my stance. As I've stated before, I shoot one handed at times meaning my head isn't on the shot line nor my bridge hand or anything. I standing up holding the cue with one hand and stroke that way.
I believe as players improve they go to seeing where the CB needs to be v hitting contact points or patches that do not exist, but where the CB needs to be does exist.
Visual muscle memory if you will.
