It's like in the Canadian Football League. There were 5 teams. Another team formed. They wanted to be called the "Roughriders", but there was already a team named that. So what did they do? They called themselves the Roughriders, and then there were two teams named that. WTF. (well, that's kinda how it happened)
Along the same vein of thought, I strongly dislike having to qualify the word "Indian" by placing "East" in front of it just in case some idiot thinks I'm talking about Native Americans.
