Microspline cassettes

Just giving my microspline cassette a clean, are these teeth meant to reduce down like that, or have I stripped them somehow?
I can't find a picture of the back side of one online.

I definitely installed it incorrectly the last time I had it off, leading to this which I feel may have stripped the cog: https://gopro.com/v/2qnB9m2eE7D9d

The reduction is so uniform it looks like it might be made that way, but there's also definitely some non factory scratches in there.
