It's canon. The Greatsword of Artorias is the original blade that Artorias used during his knighthood. When he began hunting the Darkwraiths, he needed a way to hunt them in the Abyss. Thus he "joined a covenant with the creatures of the Abyss" in order to traverse it. However, the process cursed his sword, turning it into the Greatsword of Artorias (Cursed) version. An undetermined amount of time later, he traveled to Oolacile to combat the Abyss that had begun to emerge, probably since he possesed both the Covenant of Artorias and the Silver Pendant and thought himself safe. But he was overwhelmed by the Dark, and be came fully corrupted. Thus the Abyss Greatsword was created from his greatsword, now the cursed version, being fully tainted. It's chronologically impossible for the events to occur any other way.
