I've seen channels that change the titles of their own videos (I think it was one of the PBS-run ones) explain why they do it; it's just experimenting with what titles get the most views.
Regardless, it seems safe to assume that any release these may ever get that is not subject to a search algorithm (physical media, on-demand streaming service) would use the intended titles.
