Same as on the E9X M3, the degrees swept are also smaller at higher speeds. The main difference is that the transition is sharp at 120km/h on the M3 instead of being progressive like on the Audi gauges.

It actually is the opposite, it just slows down the needle more at higher speeds...
I still think that it is mainly to provide more precision in the "useful" portion of the speedo.
