Nadal has almost 2 times wins against Fed than he does against him.
I can compare all this with boxing.
For example I am Lenox Luis , and in my prime years, there is no any boxer who can beat me and because of that I get numerous titles. After some time new young boxer comes , for example Vladimir Klitchko and he kicks my ass dozen of times.
Does all my titles won mainly against weaker boxers makes me better than he ? I think not....
H2H is more important. Especially between champions.
You don't get the point do you?
