'Yes, dear, you would have. I would, if I'd been the same person then as I am now. Or perhaps I would -- I'm not certain.'

Am I missing something? I glossed over this thinking he said "perhaps I wouldn't" at first but then realized it says "perhaps I would." Isn't that just repeating the same thing he just said? So why is he saying perhaps? Or saying he's not certain when saying in both cases that "he would"? Maybe I'm slow.
