I suppose you also lean the side walls in slightly more than in the rear. Could it be that this effect is supposed to keep the difference in rolling radius between front and rear (I.e smaller in front) closer to what it is with stock summer wheel/tire setups? Seems a bit far-fetched but I cant come up with anything else.
Could be to increase understeer for winter driving?
