True although 3 out of their 5 matches that year were still on clay, so it's not like Federer was avoiding Nadal on the surface.
I remember Federer had actually played very well in his opening match at Rome that year against Almagro (who had caused him a lot of problems in that same tournament the year before), so that defeat to Volandri really did come out of nowhere.
