True, but it has never been officially confirmed for a long time. With an official confirmation, we can finally add this under trivia section for the episode. It's still not mentioned on the episode's or any page on the wiki because before we were waiting for the "Word of God" (admins didn't want anyone to add this because it could've been just an animation goof as well).
