That's their design.
They all do that when there's a lateral impact.

There's multiple points.
To allow it to slide in a lateral impact.
In all cases where it's happened, the side of the cabin is on the floor. The cabin is usually always parallel to the floor.
Easier egress? Stabilises the wreck after a crash to prevent further flipping or spinning? I don't know.
Best guess is absorbing the energy of the crash.
The rate of left rotation is unknown, but markings on the ground indicate that there was a single impact and that the helicopter struck and rolled in place, with the rear portion of the landing gear embedded in the ground. The linear and angular momentum was absorbed by the landing gear, spreading the skids, with additional energy absorbed by the fuselage sliding across the skid tubes.
