I guess it must assume slippage in the wheels. If traction were perfect on a solid surface, presumably nothing would be kicked up. Because most surfaces have some debris or “mud”, there is slippage causing the wheels to fling it backwards. The mudflaps then deflect it back down.

The deflected mud is roughly travelling at the same speed as the truck at that point (whereas up till then it was being flung backwards at some speed less than the truck — or negative speed as the case may be).
