The star-wheel adjuster position is switching from left side to right side of the car has to do with the fact that the backing plates are the same left to right (single part number). Since the star portion of the adjuster is static (doesnt move side to side), it has to line up with the hole in the backing plate. So when the backing plate is on the left side of the car, the adjuster hole is towards the secondary shoe, so the star portion has to be installed towards the secondary to line up with the hole.

On the right side, the same backing plate now has the hole closer to the Primary shoe, so the star-portion of the adjuster has to be closer to the Primary shoe to line up with the hole.

The adjuster simple expands and contracts based on how the star portion is turned. It doesn't matter which way it goes it from the braking operational standpoint. But it does mater so it lines up with the hole in the backing plate so you can reach the adjuster.
