can someone explain the physics/logic behind this ?

Stiffening up the rear/loosening up the front allows the front end to load up more during weight transfer. Since the front end is "heavier" during maneuvers, the front tires have more grip. Likewise, the back end is "lighter" and will break traction sooner, providing oversteer.

Same logic applies in reverse.

Also consider that a suspension system generates more negative camber when compressed. In a corner, more negative camber more-or-less equals more grip. In a car that is very stiff up front, the camber will not change as much and less grip will be available when the weight is shifted to the front. A car that has a looser front end will gain mechanical grip as the negative camber increases.
