Izzy also can levitate herself. So yeah, Starlight Glimmer's cutie mark switching spell still works.
Even the episode also show that Sunny & Hitch switching jobs to see who has the harder tasks.... wink wink, Celestia & Luna when they all thought it's all smiles & at night giving sweet dreams in the Dream Realm.
