It is because the thread-based discussions features actually have two links to your message wall. One is your name and the other is something they named the "subtitle". Some wikis make use of the subtitle section and actually display something there using customized CSS/JS. However, by default, it is simply a link element with no enclosed content. Since it has no enclosed content, it is "invisible" to the casual user but not CSS.
