The whole point is that the person in question was not incorrect at all, they simply used one of two perfectly accurate descriptions when you preferred the other. Your description of them as having been incorrect was incorrect. (I note, though, that you have since edited the personal insults about he fitness of the poster you purported to correct for their prior job from your post, which would be commendable were it not directly linked to your dishonest pretense that that insult did not exist and that a reference to an insult in your comment must be to the mere act of proposing a correction.)
Also, the person in question was not me, I'm just the one who called you out on the error in your “correction”. So for someone so critical (incorrectly) of others’ failure to pay close attention to detail, you are doing a poor job of demonstrating attention to detail.
