Mandalore calls his clan the "Ordo Clan" as in Canderous Ordo!. Kreia even says it's Canderous Ordo. Did you actually listen to any of the dialog?

I beat the game as a light side male, and I don't think she ever said he was Canderous Ordo. I don't even know what "Canderous Ordo" is, or why it's significant that Mandalore is him.
