Does it though? All of spotlight's extra functionality seems to work even with wifi turned off. Even things like currency conversion rates seem to be stored locally.
EDIT: I just noticed I have spotlight settings turned off. Unless I forgot turning it off, I was either asked whether I wanted to turn it on, or it's off by default now.
