[Primus inter pares]

I just want to ask, what does the title "Global Moderator" mean?.
I know that administrators have the supreme power as the forum C.E.O.s, and that super moderators does have power over the bigger parts of the forum (zulags), and moderators does have power over the parts in the different zulags in the forum (fancorner, general oddworld discussion),
but i do not know what does the global moderator does, but my theory is that: The global moderator are like the minister president (or prime minister) in Russia, and the administrators are like the president (here in the forum we have more then one president).
