No the samurai looking one was Byakuyas because he did the thousand cherry blossom blades thing. Then the Byakuya clone was never seen again. There is no way they can explain a Byakuya clone being someone elses Zanpaktou and his Zanpaktou being a samurai could be the case but then the one that looks like Byakuya has no pair. It doesn't matter if they all don't look like their respective shinigami, some obviously carry the features of their shinigami and having one look like exactly like Byakuya is significant enough to warrant some questions and not dismiss them as 'lol but they dont look like their shinigamiz'
