... R2 is never referred to as "R2-D2" in ANH (at least I don't think) so it's certainly plausible that Obi-Wan just is confused. I mean, he has been just chilling on Tatooine for 20 years, lol.

Maybe you should watch the movie again. ;)

"And I am C-3P0, human/cyborg relations...and this is my counterpart, R2-D2"
- C-3P0 (Star Wars: A New Hope)

"R2-D2, it is you. It is you" C-3P0 in the sandcrawler- ANH

"R2-D2, you know better than to trust a strange computer" 3P0 again in ESB
