[Plugin: WP Super Cache] Cached files and logged-in users; will they still be served?

I just have one question about the supercache plugin that shouldn’t be too difficult to answer, I don’t think. It’s probably a non-issue, but I’m paranoid about settings. In the event I have to look at my site while logged in, with the option not to cache pages for logged in users, will the already generated static page still be served to anonymous visitors? Meaning, if I have to look at my front page to make sure something I’ve added doesn’t break, and you visit the site, will my having had to visit the index page clear that page from the cache, requiring it to be regenerated, or will the older, static file still be served until expiry?
