Well, true, but there are a couple of key things missing from this. The first is that Nadal withdrew from what would very likely have been an 8th loss in a row in Miami, when he realized he would have to first face Lendlized Murray, with Djokovic waiting for him in the final.
The second is, while Nadal won those matches, and deserves credit for them, four of them were on clay, and none of them were on grass. In fact while Djokovic was making the latter stages of Wimbledon, Nadal was going out first round during this time. And lets not even discuss the killer mode Djokovic was in, in the YEC of 2012, Nadal sitting out that period with an injury. Djokovic beat Nadal on every single surface, including straight setting Nadal on clay multiple times.
And I like how Djokovic's run is always said to be in 2011, when he beat Nadal in 2012 for a slam title, nonetheless.
