It's intentional in a lot of solid axle race formats on tracks with both left and right tight turns.
It removes the undesirable fight between the inside and outside wheel taking a different radius around the corner.
It also results in accelerating or braking torque vectoring from the outside rear wheel.
On longer radius turns the difference between the radius the left and right follows is significantly less while on tighter turns it is more pronounced.
Navigating a set of narrow hairpin switchbacks in a solid axle vehicle with fat tires getting that "kiss" of the inside in almost no contact while feathering the throttle will reduce scrubbed friction and leave more grip for cornering.
On the other hand in high speed long radius corners with a high powered vehicle having the inside rear floating is not going to be desirable as the heat of that power will be going into one tire.
To understand better find a vehichle with a locked rear axle, doesn't have to be a car.
Hold the steering to lock and corner at half a MPH.
Do it again at the appropriate speed to get a good weight transfer going, feather on some throttle and do not skid the outside tires and the resulting corner radius will be tighter at full steering lock than when creeping it.
