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).
