I don't think Kubo would go through the trouble of letting Shûhei achieve Bankai, just to get it stolen in the first fight. But he did that with Sasakibe, so who knows.

But I feel Shûhei is too important as a character to just get it that way. He's one of the strongest lieutenants and have already run Squad 9 himself after Tôsen left, before Kensei got his former position back.
