I think he meant the personal name by which Sauron was known, not just something like "the Dark Lord", or "the Top".
I still favour the idea that the ban on calling him Sauron was only in effect to prevent underlings from having any sense of a personal relationship or understanding of their master. Sauron wanted to be impersonal; godlike. Not being able to name him would have the effect of making him seem even more fearsome and remote to his troops.
