From what I can see in the diagram, these shots are both on opposite sides of the border of using C with an inside pivot. No need to have such an extreme example, you can move each one so that it's a little more toward the heart of the C range and demonstrate the same thing.
This to me is the key issue with (and benefit of) the Pro1 system and the source of many arguments, especially when looking at things in 2D terms. I use it, it works, but just look at the shots for a minute - we have two distinct shots the same distance apart in two different locations at two different angles being shot into the same pocket. From a relative viewpoint, the CTEL and edge to C picture should be the same - in other words, the "tunnel" created between the CTEL and edge-to-C lines should be the same. So how can the balls both go in at such obviously different angles and paths to the pocket?
There are only two differences I see - the relationship of the balls and those CTEL and secondary aim lines (the formed "tunnel", or singular 360 view of the cue ball) to the pocket, and the initial position of our body. Something in that relationship is what must be allowing the exact same perception and movements to result in cutting one ball 14 degrees and the other say almost 30.
Maybe there is another variable I can't think of right now. I just know I've given up trying to figure it out, it can be proven at the table, and as I've said before if there isn't some weird math/geometry at work then there is a pretty cool visual trick at work where we are able to visually orientate ourselves very consistently and accurately to these different shot lines without perceiving any sort of feel based movements or tweaks.
