Well, it isn't directly stated that Antonio leads the Assassins in Venice. I like to think not, and that they are simply senior members of the Brotherhood, and not really "leaders". It's always said they are merely members of the Brotherhood.

But yes, Ezio is nothing more than a Mentor in the Ottoman Empire. Yet because of that, he still has a lot of respect from the Ottoman Assassins and quite a bit of authority over them.
