Of course I can see a line from the left edge of the cue ball to the left quarter of the object ball. What I can't see is how it's supposed to help guide me to where my eyes should be located according to the system - unless it's just somewhere between the two positions needed to sight along each line separately, and that's not precise enough for aiming in pool.
Eye dominance may not apply to interpreting 2D pictures (I'm not sure either of us knows), but it certainly may apply to interpreting 3D real life where this system is supposed to operate, especially when trying to determine a (so far undefined) position between two lines.

OK I think I have a way to describe the system, and why there is so much conflict with it. Or not, but I'll try
How (I understand) how this CTE system is supposed to work:
1) identify the shot determined by cue ball, object ball, and pocket placement. (left cut, right cut, A/B/C)
2) move your head/eyes/body into position so you can see both lines (CTE and ET-A/B/C)
3) move straight into the shot, keeping these visuals in sight, and position the cue 1/2 tip left/right, then pivot to center.
4) shoot.
So the big question is, where are you aiming when you move into the shot? Showing this line on a diagram probably won't help much because (when down on the shot) it can
look slightly different for every person. Everyone has their own eye dominance, and their own way of perceiving a 3D perspective on a shot. However, there is only
one line of aim that will work, and that is found through practice. Once you have it, you are locked on. You use the exact same visual and movement into the shot once you know where that is for
you.
The aiming itself is not unlike the ghostball system: you line up your shot to the ghostball however your mind/body does it, and shoot. Shoot and shoot and shoot until you are happy with your shot making percentages. Same with CTE: line up the visuals, get the cue and bridge in line, pivot and shoot. Shoot and shoot until you find it.
The difference with CTE and ghostball is that there is only a handful of visuals you need to learn (CTE, CBE-ABC, 1/8ths) whereas ghostball is infinite. CTE gets you shooting center pocket much quicker than a million shots. There are many shots that are not so easy to line up with ghostball, whereas CTE you can line up any shot since you are just using the cue ball and object ball as visuals upon the actual shot. With CTE you have two very strong lines of aim on your visual, whereas ghostball you have to imagine a ball to shoot at, and this gets very difficult on long and thin cuts.
