Think you're looking into it a wee bit too much if I'm honest, everyone was going crazy and just making joke posts for a long while, and I don't think anyone really bought into Cao Cao's roleclaim at that time. I think Zhao Yun was just joking about. Still, he could come in and tell us he wasn't joking, who knows? For now though, I don't want to scrutinize it too much.
