As I understand the template theory, they should have had seperation on that tail in the first 6", yet flow remained attached for a good 4'.
Excellent observations.

Maybe a case of theory not matching practice or reality?

I agree the whole bow pressure build up on purpose so that the airflow clings to the aft body is fairly non-template friendly to say the least.
