Yes, but it is possible of course they created characters for both worlds (since Riverview was available right away they must have been working on both worlds simultaneously) and then maybe last minute decided to move George to his firehouse in Riverview? Like the Kent household, that was featured in a promotional video before Sims 3’s release (Kim Kent, Piper Hipp and Liam O'Dourke). This household was not included in the final product (though they were available for download) and then Liam showed up as a townie for Hidden Springs years later.
