You take that same drivers side rear CTS-V caliper and rotate is 180 degrees to mount it on the rear of the axle, the picture on the right, Piston #1 now moves to the bottom of the caliper and the cross-over tube to the top. Rotor rotation remains the same, so as the rotor rotates forward, it still hits Piston #1 first.
This looks like it keeps the leading edge orientation as you stated above. What am I missing here?

You missed nothing and your illustration is spot on
