So it kinda makes sense that he was blowing through all of the eyes and jutsu's, as Itachi would say 'to test his limits and abilities'. Him using so many of Harashirmas techs make sense too, he's like a kid in the candystore of the highest know Kinjutsu's to exist. He was unbeatable to the Kages they actually stood no shot.
