If you're talking about visually aligning the CB center with the OB edge (so one is directly behind the other in your sight), there is no change as the balls or your eyes move back or forward. The CTE line is constant, and if you're looking along it, so is your perspective relative to it.
Here's a couple of 3D diagrams to show what I mean. What am I misunderstanding?
