Nah, that was just an example. There are plenty of Hondas sold in the other 49 states that are ULEV, PZEV, SULEV, etc. They just happen to meet California emissions requirements.
It shouldn't cause any concern in buying the car, they have exactly the same engine. Minor programming tweaks, like Jim said, may have allowed it to jump through more emissions hoops than the other
