Like so many things, that work in theory, in practice, the theory dosent really hold up that well, Two pins could take each a half of the pressure, and either of them could be set first.
Remember that the plug is in the cylinder with one or two thousands of an inch tolerance between the plug and the cylinder. your tensor blade applies the tension at the front of the locks, and the binding force will be stronger there but the length of the plug can be seen as being on the tensor and with a greater wiggle the further back you get from the front of the lock,
think of the tensor as the stem on which the plug is mounted, and the farthest end of the plug is capable of moving in that .002" tolerance while the front of the plug is pinned down by the tensor.
This sort of thing is not taken into your original theory, which is also affected by damage to the lock, defect on a micro scale that may be present, lubrication, dirt, rust, sticking parts of the boltworks, and sometimes counter rotation springs in the boltworks. The theory has so many exceptions to the rule that its not worth thinking about this simple theory.
Wake up and smell the Kafka!!!
