Sekai does not have dual meanings. You're making things up now. It literally means "world". Your example doesn't prove a dual meaning. In fact, I'd trust someone who knows the language over some internet website anyday. Regardless, they're aliens. The end.

Edit: For the sake of good debate, let's say you're right. Sekai means "society" and "world". It literally makes no sense, logically, for the context of the databook entry to mean "society". The only logical conclusion, given the context, is another "world" (which is what sekai is translated as 99.999% of every time it is used anywhere). You can grasp for straws and continue to drag on debates, which you propagate because you a desperate to find a meaning that validates your own personal denial, but it doesn't change the fact that this is not open for interpretation. The clan came from another world to earth. That's just a fact.

If you refuse to believe that, then I don't know what to tell you, because we don't change fact based on someone not liking that it is indeed a fact.
