My least favorite type of Nadal matches is playing on hards against the likes of Diego, Nishikori, Simon, etc... even Ferrer and obviously Davydenko. They're not exactly the same type of players (some play radically differently in fact), but they all move so well and can rally with Nadal, and they really annoy him once they take the ball very early (Davydenko is a master and he naturally takes it super early so he really was a bad match-up for Rafa). So this whole fiasco doesn't surprise me. In fact, I expected it. Wouldn't put too much stock in it though.
