Wrong. As Roger has slowed down, it is his defensive game (passing shots, defense to offense transition etc) that has declined the most. And he is still an offensive player with a good serve - and as such, he prefers a fast court.
Basically, if a powerhitter such as Delpo or Berdych is on fire, it doesn't help Federer much if the court is slow - he will still lose. The only way Olderer can still defeat these guys is taking the initiative from them so they don't have time to set up their shots. And it is easier for him to do this on a fast court.
