The flow should separate right there with no hope of re-attachment.It's just too steep.

Thanks for your additions.
Looking at the Citroen aerodynamics article from a few posts earlier, they mention lowering drag and lift by adding a rear "aerofoil" (spoiler) beneath the rear window on the CX. This reminds me of the Crisis Fighter Pinto with its rear spoiler to improve drag on its too steep back glass.
If Ken tuft tested the back glass on his SM wouldn't the tufts show turbulent flow?
