I'm very suspicious of this claim. If I and seven other own a piece of property, I alone cannot sell it to a prospective buyer. The same would hold of copyright. Although each
owner
has a copyright, a single owner cannot grant away the entire right to a
third
party.
It also doesn't sound right from the practices for free software - where relicensing is a massive pain in the backside because of the need to get agreement from al
l contributors. Hence the "or later" language recommended for the GPL - and the GFDL, hence a mere vote on relicensing being possible.
Free licenses are generally written from the point of view that modifications to works constitute derivative works, and not works of joint authorship. Either is certainly possible. The key legal question is whether the authors intended to collaborate on a single work (Lennon/McCartney), or if one author created a work which was then modified by another author (a movie created from a screenplay).
It's by no means clear which better fits what happens on Wikipedia. I could see things going either way, but considering the use of the GFDL I'd lean toward believing that the *intent* of most authors was for each subsequent edition to be a derivative work, and not a work of joint authorship. And that's what matters, the intent of the authors (unfortunately, some authors probably intended different from other authors).
