My Reese hitch wrap around jaw has three levels on the inner surface of the jaw. At the top the diameter of the jaw is large enough to circle the largest upper part of the pin. The next level is smaller diameter to circle the smaller part of the pin. And the lower part is again larger to circle the larger part of the lower portion of the pin. Thus the jaw matches the contours of the pin and basically traps the pin in the jaw. But that contour does create something of a cup on top of the jaw that the pin could sit down in if high hitched. With 3,000 lbs of weight on that pin sitting in the cup, it could ride for long distances and never come out if there were no extreme bumps or distorted movements. And even a normal pull test would not indicate a problem.


Again that is why I always have the pin box slightly lower than the hitch so that it rides up on the hitch and ensures no high hitching.
