If by "the same enemy" you mean the Sith, then you could apply that to every single [post-5,000 BBY] era of the entire Star Wars timeline. Either way, it still doesn't make sense because there's been numerous Sith Orders and the True Sith never appeared in either KOTOR games, anyway. On top of that, they were never even confirmed to exist until now.
