It's a small mistake anyway. Also you could excuse it as not being a mistake with: "a previous anime episode showed Naruto teaching the Rasengan to Konohamaru during Part II. so even though it's not consistent with the manga, Studio Pierrot is being consistent with themselves" or so. EDIT: in the same way as Utakata arc and then Studio Pierrot making Utakata recognize Naruto when Edo Tensei's in the anime, or Ino's knowledge of Katsuyu etc.
