Unfortunately, not all veteran officials have mastered being helpful AND being tactful. Just nod your head and say, "thanks for the information." If you think it's good info, add it to your game. If you don't think it's good info, just let it go in one ear and out the other.
Even though it sounds like this official isn't a great teacher, he/she is under no obligation to help you and you should at least appreciate the fact that they are taking the time to try to give you some help.
