I think he just got a call from the studio. He was causing a lot of negativity before the film and the studio probably told him to stop.
Maybe. Or maybe he realized the journey wasn’t so bad after all. We don’t know. It doesn’t change the course of the events of the film. It appears that he’s coming back for IX so it doesn’t matter. Besides, just jumping to these conspiracy theories is not healthy or productive in any way, shape or form.
