Yeah, it means that Nadal even at his very best cant beat Federer on a true fast court where the real tennis is played (or used to be played). If they hadnt slowed down Wimbledon at 2001 and all the hard courts after 2007, Nadal couldnt have won any other slam than French and Federer's domination over tennis would be much more wider and longer.
