See how it looks like KH2 Sora and Riku are at the Keyblade graveyard before they jump at Xehanort? Was this just for the sake of video transition? Everything else they showed was accurate, but Sora and Riku were never there fighting the old MX obviously. Maybe this is foreshadowing how Sora and Riku will team up to defeat Xehanort?
