It is.
GPL lets the original author choose how new versions apply to the software. See paragraph 9 of the GPLv2 [1].

If you choose "or any later version", this is no longer GPLv2 (which means GPL version 2 only), but GPLv2+ (with the more-or-less official notation). -- Vincent Lefèvre <vincent@vinc17.org> - Web: <http://www.vinc17.org/> 100% accessible validated (X)HTML - Blog: <http://www.vinc17.org/blog/> Work: CR INRIA - computer arithmetic / Arenaire project (LIP, ENS-Lyon)
