This is because there is no one stated phrase or explanation that resonates the same amongst different shooters. It's like taking someone that has never ridden a bike before, and "explaining" to them, in plain english, how balancing a bike works. All you can do is give them the basic steps, and let them discover for themselves how to balance.
So in the context of CTE, the 5 shots. Each one uses the same descriptive alignment for a given pocket, say CB edge to A. If you setup these five shots, and go behind the CB and align CB edge to A, then freeze and note how your are physically aligned (where CCB overlaps/misses the OB), then repeat the steps for each given shot, you should see that each progressively thinner shot, starts with a progressively thinner physical alignment. This isn't something you do consciously, it is the orientation on the 2x1 surface that presents this. If you don't see any differences, then you really are slightly adjusting to what you think you are expecting to see. You have to learn to let your eyes do the work, and focus on the real, correct alignment. It's all there, but it does take some repetition/experience to see it. Once you do, it is repeatable all over the table, for differing perceptions, and banks, and so on.
