Yes, the .mp3 is exactly the same, I see it sitting in the streammusic folder. However, it doesn't trigger properly in-game. I had a look at the .git file of 835NIH.mod and it's still set up to use the same Sith theme as regular Ravager levels.
I assume the a_mus_visas.mp3 was meant to either be played via a trigger, or the change in the .git file was simply omitted by accident.
Here's a video I've recorded of that cutscene, as it appears in my game - https://www.youtube.com/watch?v=qrjBgqtSF_c
