Didn't Ichibei said that Ichigo became a true shinigami? Meaning that he could have lost his quincy and hollow powers. We still don't know that. But when Byakuya activates his new bankai with the armor, you will see my point.

Let me resume it: When a shinigami achives his true bankai, the user takes somehow the form of his zanpakuto form or powers, like its been said over the years the zanpakuto and the shinigami are one and the same.

Edit: Yamamoto's Bankai power is flames that are condense into the edge of the blade. Second stages activates also automatically, which means he is wearing it even if the opponent can't see it, is still there. Fake Yhwach's sword got destroy after touching Yamamoto's invicible flames.
