It's all about friction. The rear tires, if they have less grip, will slide before the front tires do. An object will *always* rotate around the point of highest friction (front tires). So, the laws of physics are making the car want to swap ends. Snow tires only on the driven wheels might make sense for RWD cars, but I know of no tire or carmaker that suggests doing it on FWD cars.
