Wiki Activity only shows so many edits, so if there's lots of editing going on in the Wiki it will eventually "push down" the new page and be replaced with the "newest" edits in activity.

So if you edited 10 different pages, it would all show up in activity (at the top) above the new page you made. So in a week it'll more than likely disappear (if it's an active wiki) :)
