Indeed, the required data are downloaded from the server the first time
you ask for them, and are stored in a cache on your hard drive. Then,
Mathematica needs to go online only to check whether they have been
updated (but the check can be turned off). From the online documentation:

"When you click a link to a documentation notebook or call a data
function like CountryData, Mathematica knows whether a newer version of
the information is available on a Wolfram Research Paclet Server, and if
so it will download and install the update automatically. In the case of
smaller paclets like documentation notebooks, this is often so fast that
you will not even notice it happening."

See "Mathematica Internet Connectivity" at
http://reference.wolfram.com/mathematica/tutorial/InternetConnectivity.html,
or select tutorial/InternetConnectivity in the documentation center.
