California and Indiana are simply the names of the towns, same as the other SSHE schools. It's kinda like the towns named Egypt or Lebanon.
The Cal president wanted to change the name a few years ago (because "people don't get that it's in PA) and everyone got VERY pissed off. The thing he wanted to change it to not only would have gone against naming conventions, but wouldn't have done any more to let people know it was in PA!
