Yeah. The part you quoted is the most funnier part of the GPL (given
that I don't "modify" anything [as far as copyright law is concerned]
when I "combine" works, etc.). The "grantback" is formulated in 2 (b)
and the next statement.
But when you distribute the same sections as part of a whole
which is a work based on the Program, the distribution of the
whole must be on the terms of this License, whose permissions
for other licensees extend to the entire whole, and thus to
each and every part regardless of who wrote it.
I have no idea what the FSF means by "sections" but they state rather
unambiguously that <quote> a "work based on the Program" means either
the Program or any derivative work under copyright law </quote>" (see
Section 0).

But with a permission to copy and give the same rights to everyone
(including "A"). Put the lenses on, dak.

Yes, "A" must acquire a single copy (or that funny "written offer,
valid for at least three years") to have all the rights. But the
copyright grant doesn't extend to "unrelated works or preexisting
(and therefore necessarily nonderivative) works". And using the
copyright license to extract such rights exceeds the scope of the
copyright grant.
