Does that give you a file that will play in Kodi in 3D SBS then?

No, it is not just SBS it is actually the original non compressed or reduced stream of the movie. In other words exactly as it would be on the Blu-Ray.
That is the great thing. You have to name the file SBS so Kodi will pick it up as 3D.

This is perfect especially for branched titles, like Disney stuff - which would be troublesome playing from ISO with a light Menu.

Give it a try, you will be amazed how easy it is and how well the Pi performs.
