That version is a "workprint" - a not-complete edit of the film. Sometimes workprints are the complete versions picture wise, but stuff like ADR, SFX and music tracks are not yet added.
I have a few workprints in my collection - the best ones being Hulk (not all the CGI is complete and when he is whizzing the tanks round his head, his trousers disappear showing hulk butt), and the first 2 episodes of Season 5 of Angel - all the wires from the stunt work are still there and some SFX is missing. Sometimes they can be a better watch than the finished version.
Going back to Kill Bill, the other version I saw went black and white when Uma Thurman went medieval on those chinese guys with the sworRAB - was that deliberate or is the final version in gory bloody techicolor?
