Whoever starts X is the only one who has rights to talk to X, or enable others to talk to X. What's the mystery? The "-" in "su -" means "Make the shell a login shell", which is straight out of the man page. When you "su", you are elevating your rights to that of root. When you "su -", you *become* root. There is no subtlety. You are no longer you.
