I am mistaken. The links DO pass each other. That's why they're shaped a little like a figure 8 - to provide clearance. This design is cleverer than I thought.
The thunk is also identified. Earlier I talked about the drop down gravity bar that holds the hitch straight when the hitch bar is not in place. That bar is held in place by a pin which is mounted in two ears on top of the black piece. At the limit of travel, one of the side links interferes with the nearest ear. The ears and the drop down bar are all pretty hunky, so the overall width of the 'stop' is about 1 1/2"
The fact that the links pass each other also explains the s-shaped locus of VPP's. Tonight I learned that the original creator of this design was very clever indeed.
Apologies for the earlier misinformation.
