The pinch bolt goes into the groove to insure the stud does not pull out (sounds dirty). Ideally you would want the sleeve to also be held by the pinch bolt. I am assuming that the groove is also .022 smaller
That groove is the only thing keeping the stud in the knuckle when you install the smaller ball joint since the pinch doesn't close enough.

The pinch bolt applies pressure to the two sides of the knuckle to hold the ball joint pin in the knuckle.
But at only 37 ft lbs if torque it’s the fit that holds the pin, to loose and the knuckle could crack.

I am talking in-out not friction. The bolt in the notch keeps the stud from dropping out because 37 ft lb is not much to cinch it. It is what has saved all of those that put LS/LT ball joints on, without the bolt in the notch the LCA would be on the ground after the first bump in the road because the pinch was not pinching.
