I would imagine that the disck rotor and the freewhell are spaced the same
Quite possibly. In which case why have different flange diameters at all.
Although I suspect the disc side is flater. You could flaten the side with the screw on free wheel to match. But you'd lose more in bracing angle, then you would gain in even tension (total guess).
Its probably marketed as providing a stiffer build with regards to braking. But I'm not sure I buy it.
