If you change to root in an xterm using su or su -, root is given a copy of this "magic cookie". (There will be a file created in /root called .xauth<something>.) This gives root access to the X server. If you log in at the cli, without having changed to root in an x term, root will not have a copy of the current cookie. Also, this "magic cookie" is generated each time a user logs in using the gui, or starts X from the cli. Each X secession has its own "magic cookie". You can see what file contains the "magic cookie" by running "echo $XAUTHORITY". This is a security feature. You can man xauth for more details.
