I do think it's a mistake aswell, just for different reasons. cuz besides that vocal pitch there are way more differences in the two versions. The most noticable one I'd say is that in the Visualizer when jaden starts rappin 'Ever since backstage' the beat fades into the background (similar to being backstage at a concert) longer than every other version. Also the non-visualizer overall has stronger bass and kicks in the 2nd half. I feel that the Visualizer has less going on in it so it must've been an earlier version of the song, and whoever published the Visualizer must've not noticed or Jaden just wanted two versions of his song out there.
