OG Xbox BC on X1 is clearly built on the emulation work done for 360.

I don't know about all of this but KOTOR plays flawlessly so far :) (maybe 12 hours in)

That's all I need from this mediocre emulator

If you watched the video you'd get an idea why people disliked that emulator on 360. On X1 though, primarily thanks to a MASSSIVE performance boost, its less than mediocre now. I'm assuming they're doing work to fix bugs as well. But it seems like they're starting with the well emulated stuff first.

KOTOR happens to be one of the most desired games and that was an ideal game to launch this service with.

While the emulator was kinda mediocre, it was still a useful feature on 360. I used it to play through Jet Set Radio Future and it was mostly fine.

I have a physical copy of KOTOR and I look forward to using it on my X1.

I did not know it existed on the 360 :) 

Actually when you buy the OG game (Kotor in my case), it says "play on 360". So it makes a lot of sense (your OP)
