I'm guessing they based their claim on the item's picture. Japanese style sword, black background, pink flower petals and a rippling pattern surrounding the blade... there's a definite visual similarity.

But seeing as YG has nothing else in common with Byakuya, his powers, or anything else in Bleach, it's a bit of a stretch to say that the item is "copied" from the series.
