According to the POSIX and UNIX standards, the above command asks to display all processes with a TTY (generally the commands users are running) plus all processes owned by a user named "x". If that user doesn't exist, then ps will assume you really meant "ps aux". The warning is given to gently break you of a habit that will cause you trouble if a user named "x" were created.
