It's not _very_ odd: A copyright holder attaches licences to
_instances_ of a codebase he/she issues and distributes.
Daniel Barron could issue one instance under GPLv2, one under a
proprietary licence of his choosing bundled with support and upgrade
service entitlements, etc. He could cease to issue new versions under
GPLv2 at any time, if that suits his desires. (Other people could then
fork the head code, if they wished.)
