"[Visitor]" appears in NPC chat

At SXSW today I saw someone in chat with an NPC and the yellow [Visitor] appeared in the close-up chat window. This confused the person who tried to ask the npc about what Visitor meant. It is probably not useful to display the player's name that way in an NPC's conversation, but apparently is confusing.

 

Furthermore, an NPC that first met your toon when you were a visitor, will continue calling you visitor even after you purchased an account.

 

At least the "my name is" should fix that, but that does indicate perhaps where the conversation system is getting the name incorrectly. I wonder if something like this ever happens to PVP players, but if it did, I think I'd hear about it.
