No, because the assignment agreement says that the FSF "agrees to
grant the Assigner non-exclusive rights to use the Work (i.e. the
changes and enhancements, not the program which was enhanced) as it
sees fit". And, indeed, this is commonly done. For example, Cygwin
had two different license agreements, one when it's distributed by the
FSF and one when it's purchased by Cygnus.
