I replied to him, so by saying "Look at his name" I am implying to your name, not his, because he replied to you. If I want him to look at his name, I would have replied "Look at your name". If I wanted you to look at his name, I would have replied "Look at his name" to you, not to him. The point of my comment is to tell him that you are baiting, because you clearly are. Why did I reply "Hello" to you? Look at YOUR name.
