Edit: it turns out that after the release of the Ultra HD blu-ray, Amazon Prime video actually lists Advent Children complete, and it actually truly is advent children complete, not the original movie. My question has been answered

Nomura and others began experimenting with concept sketches and CG renders of the film's key characters and locations. The film's subtitle was originally going to be "reunion", but Nomura found it did not suit the rebirth of Sephiroth that was planned for the film. He found the word "advent", Latin for "arriving", and Nojima wanted the word "children" in the title as well. Thus the full subtitle "advent children" was created. With the project rapidly expanding, a year after production began the script was still not finalized and scenes and renders were still being altered.
The term "Advent Children" could refer to the Remnants of Sephiroth, the children of Jenova who bring about the coming of Sephiroth, or to the Remnants coming to the Planet. It could also refer to the children recruited by the Remnants to search out Jenova to bring the advent of Sephiroth.
