Right. Note well the subtlety in choosing the words. The above FAQ does
*not* say “If the FSF considers a work non-free …”; rather, it says “If
a license is inconsistent with the FSF's four freedoms …”. This
determination then doesn't depend solely on FSF policy.
Remember that the FSF chooses to apply different guidelines to different
software works. They divide software works into exclusive categories by
interpretation such as “program” (what the FSF calls “software”),
“artistic work”, “program documentation”, “work of opinion”, etc.[0],
and further imply that the one true category of interpretation for a
work is to be determined by the copyright holder at the time of
licensing the work, not by any of its recipients at the times they use
it.
Based on what the copyright holder considers to be the one true
interpretation for a work, the FSF considers its recipients deserve
different freedoms[1]. This without regard for whether any recipients
might choose to interpret the work differently from the copyright
holder.
The FSF only considers works of software that copyright holders deem to
be programs (what the FSF means by the term “software”) for its Free
Software Definition.
This is why they don't see an inconsistency in their promotion of the
non-free FDL. They consider that if a work's copyright holder deems that
a work is to be interpreted only as documentation, no recipients need
the four freedoms of the FSD for that work.

The Debian Project's social contract (§1, “Debian will remain 100%
free”) requires that the DFSG applies to all works of software in Debian
(“the Debian system and all its components”).
This application of the guidelines is without limitation by what the
copyright holders say about the interpretation of the work and without
limitation on how any of its recipients will choose to interpret the
work in any instance.
So this is why the FSF might consider a work free (because it is not
deemed to be a program, so they don't apply the FSD), while the Debian
Project might consider the same work non-free (because regardless of
whether it's interpreted as a program, its recipients must have exercise
of the DFSG freedoms).
The two definitions of software freedom are compatible. What is
incompatible is who gets to determine the set of works for which those
freedoms should be considered. The FSF says the copyright holders get to
determine which works's recipients deserve the four freedoms; the Debian
Project says all works in Debian must have freedom for all recipients of
those works.
