I think those other interpretations are still valid regardless of the end scene. I imagine the original idea was to write a title which had multiple interpretations relevant to the movie. It reminds me of Return of the Jedi - is it the Jedi Luke Skywalker returning to save Han Solo and defeat the Empire; the Jedi inside Darth Vader, Anakin Skywalker, returning to save his son; or is it the implication that in the wake of the Empire’s defeat Luke can now go on to start a new Jedi Order? It’s all three, right.
