He said Four Swords came first, and clearly it doesn't, because it has a prequel. Also, I think he actually said it about FSA, although I might be wrong, and as far as I know it's pretty much impossible for that game to be first in the series anyway. Heck, it's a sequel to Four Swords. But even then, it requires Ganon to exist beforehand at some point. So obviously the idea changed during the design process somewhere.
