The credits are for Finale Co-Chorereographers, and each is listed with a song name. I don’t know, but maybe these are the choreographers from her tours. Since that part of the show is about her tours, maybe they used the tour dances.
That may be plausible except that Jon Rua is credited for "Believe" (the only one also credited independent of the finale), and he would have been a teenage wunderkind. I don't recognize the other names.
