LPChip, I'm not trying to sound insulting here, but it seems that almost every time you answer a question, you answer a question different from the one that was asked.
The question asked has nothing to do with save points during the boss. It's whether there should be a save point after the boss or no save point after the boss. (And it's implied there's nothing to kill the player after the boss.)
At least one save point during the boss is shown to exist, but it really has nothing to do with the question.
