I mean, sure, to keep the reader interested. But still, I wish they would justify that. IE. Who is Yondaime (family, friends, etc.), how did he become hokage? Why did he choose to seal the nine tails in Naruto (I think that one was explained, but I forget whether it was in the manga, or someone assuming), Either or though, I'm thinking Naruto should have a hokage arc after this one.
