The Templar hierarchy is never clearly and properly defined; from what I gather, each Templar Rite always had its own Grand Master, and Rodrigo Borgia was specifically stated to have been the leader of the Italian Templars in the AC2 database, not of all the Templars. Because he was one of the most influential men in Europe, and later became Pope, his power stretched to all over Europe and the Borgia had agents and plans everywhere in the continent. But whether there were any other Grand Masters at the time of Rodrigo's reign is never revealed, so we should not really assume one thing or the other.
