Even without the coming out distraction, the apology is kinda weird. "Wow, if I did that, that's bad. Sorry. ¯\_(ツ)_/¯"
I don't think he would have phrased it that way if he didn't actually remember doing it. If he didn't have a reason to think he did it, he would have said he didn't do it. Seems to be a way to escape both being held accountable and accusations of being dismissive or a liar at the same time.
