Yes, but the way it is written, as a part of the section for round HSS
design, leaves me to think there must be another expression for rectangular
HSS sections that is hidden someplace else in the book.

That formula is correct. It is a modifier that accounts for any axial
compressive stress in the tube wall at the location of the connection. In
my edition of the HSS manual the definition for Qf is shown in section 8.2
just above the formula you refer to.
