I think the point is that while you were a contributing factor you are not the sole focus of his disagreement. You aren't the only moderator that does the things you do (at least, I don't think so). So yes, he COULD have PM'd you specifically about YOUR thread you closed: but I'm sure PB had several threads in mind when he posted, yours just being the last one (most recent) that happened. So while he could have gotten clarification on yours specifically, that wasn't really what he was after.. (if I'm reading him correctly.)
