That doesn't necessarily follow at all! Archie can marry Betty, or
Archie could marry Veronica, but that doesn't mean Archie can marry
Betty _and_ Veronica.*
I think the logical fallacy here comes from excessive reductionism:
trying to break up the dual-licensing of the derivative work as two
single-licensing events.

Absolutely. If either the GFDL or the by-sa allowed a dual-licensed
derived work, we'd be in the clear. If the by-sa allowed dual-licensed
derived works (say), we could ignore the GFDL and publish the
dual-licensed derived work under the terms of the by-sa. Or vice versa.
However, neither allows a dual-licensed derived work, and since we have
to use one or the other, we just can't do it.
Try looking at it this way: say I've made a dual-licensed work under the
by-sa 1.0 and the GFDL. You've made a derivative work, and you want to
relicense it under the by-sa 1.0 and the Design Science License. You
can't do that according to the rules of the by-sa, and you can't do it
according to the rules of the GFDL. Therefore, unless we make some other
agreement, you can't publish the dual-licensed by-sa/DSL work.
It's pretty easy to see that licensing derived works by-sa is OK, and
licensing derived works GFDL is OK, but dual-licensing derived works
by-sa/DSL is not. It's harder to see that dual-licensing derived works
by-sa/GFDL is not OK, either.
It's counter-intuitive, and it probably goes against the original
authors' desires. But I think the wording of these two licenses makes it
impossible without an additional agreement.

I think it's necessary, actually. I believe that 99.99% of creators
would want this in the first place. IWBNI future versions of the CC
licenses and the GFDL would consider this possibility.
