Yes, this is "We met earlier in the day, I'm saying hello again." Or, like I said, a waiter that over the course of a multi-hour dinner and drinks, continually confuses the two. (EDIT: Whoops, when revising, I apparently deleted that story. I've seen this too.)
Furthermore, it doesn't happen with other people, at least not to the same degree. People even say "whoops, I confused you with the other black guy."
Who knows, perhaps they even have an advantage because people actually remember them. They only get their names mixed up sometimes - other people are simply forgotten completely. How often do you forget the name of people you have just been introduced to?
