Could be wrong but it seems like the cam on the outside of the turn is sliding down against the sharp bend on the arm increasing the pressure to the cam pushing it back towards the centered position.
When the trailer tries to swing away from center, the cams try to move away from their centered positions.
The friction force between cam and bar resists this movement -- up to the point at which the static friction is exceeded.
Then the cams begin to slide along the bar slope with slightly reduced friction force.
When the trailer tries to return to center, friction force between cam and bar also resists that movement.
But, the friction force is significantly less than when the trailer is trying to move away from center.
