webarchive local or still live?

I’ve been looking at some web pages I stored as webarchives and thought this page was a snapshot in time of the webpage. But when looking at a page, Littlesnitch (network filter application) is asking for permission to access the web site from within DTPO. Are webarchives still “live” pages?

Dynamic parts (e.g. loaded by scripts, for example ads) might require additional resources and therefore access the Internet.

Thanks. I figured it was something like that. I was just wondering. I just set LittleSnitch to block them when inside of DTPO.
