LAN implies that your copy of SC2 does not have to check with a central B.net server in order to play games.

The consequences of this are that unofficial servers can be set up like iCCup were, allowing effectively cross region play and multiple ladder accounts per household, as well as fixing cross-region lag.

You could still connect to the official server for its benefits, but other things I listed could be provided by an SC2 iCCup.

I see. To me LAN mean Local Area Network so basically only playing on your home network.
