To be fair, Chapter 699 of the manga had the same kind of timeskip. One moment, we're seeing Neji's funeral, the next moment, Kakashi's face is on the Hokage Rock and he and Sakura are seeing Sasuke off as he leaves the village to wander the world.

The sudden timeskip in both the manga and the anime obviously isn't meant to indicate that the events of Kakashi Hiden didn't happen.
