This example is interesting. I think I am granted to reproduce those two separate works of
the same substance ("verbatim copying in quantity" in GFDL's sense). Do I have the right to
combine the resulting two copies into one? None in either license seem to allow me to do that.
If the original two poems were dual-licensed, would it be any different? I am not sure,
but perhaps not.
Since I do not have enough expertise to answer this question with certainty,
I tend to think that a safer approach to dual-licensing is to release a work under
a meta-license, or to request CC & FSF to insert a dual-licensing clause in their license
texts. I sketched those ideas here:
