If you check the chapter again, or the image in your blog, you can see the torn cloak being shed off along with the outer skin layer when Mayuri tells Nemu to get away, and the clone tearing off its thumb and speaking like Kenpachi does, has no cloak.

It seems the clones can evolve just as much as the original arm/body.
