Before you make such a definitive claim, consider this: I have an 84 Audi
5000S Turbo, and it definitely has two oil filters.  My previous 84
5000S Turbo also has the same setup, so is a friend's 85 5000S Turbo.

Not.  By the way, the Audi oil filters for the turbo cars are different
than those for the non-turbo cars.  This is true even for the main engine
oil filter.  Although Fram lists the PH2870 for all Audis, don't use that
on your turbo!  Get the genuine Audi filter.  Just one look at the internal
construction will convince you that the Fram is no substitute.

Agreed 100% here.
