I bought these dual P-Tops and replaced them with single P-Tops in all B-pillars and alternate outer pillars of the 4 x 6 centipede support frame. While not a requirement, it is best to have them on all B-pillars so you can secure the work surface. The 4 x 6 requires 3 work surfaces so without the 2 double P tops the locking pins would have to be moved to ensure all work surfaces are locked. Bora gives an illustration of how to do it, but I just can't remember where all the locking pins go. This goes against the quick setup ethos of the Centipede line of products. As said, it is not necessary to buy them, but they are very practical. In fact, I bought them to use the accessory that comes with the support leg. highlighted.
