I was able to reproduce this behaviour by returning to the Aussie site and reentering the CDHB site.
What was the Aussie site? Quite a few popups run when you leave a site, not when you arrive there. If this is the case it shouldn't matter where you go when you leave that site, of course.
Actually visiting trafficmultiplier (with cookies and popups disabled in Firefox) confirms this:
Sooner or later, no matter how much someone likes or uses your site, they are going to leave it. Clicking on a link you want them to click, or some other link. Or typing in a new address. Or closing their browser. They are going to leave.
Now you can turn that certainty to your advantage:
Now you can get credit when someone leaves your webpage. They have to leave anyway; you may as well get credit for it. (Actually, two credits.)
