What Kerrigan said. He's not wearing your markings, he's wearing his. You only see them as yours because the order of the markings in yours and his markings.cfg files are different. Think of them as slots; you could have, I don't know, say, a Llama marking in your slot A, and he has a Fox marking in his slot A. So while he sees Fox, you see Llama. Does that make sense? XD I'm trying to put it as simply as I can. The same thing happens with custom emotes.
