How can this site confirm view without cheating?

Dear all.

I have a question about technical. I wonder how this site can confirm user view?

I was tried to sniff their request via http header addon. But I got nothing

This site is rapidvideo.com

The site redirects me to google

I have a problem that I can not solve.

Here is link: www[dot]rapidvideo[dot]com/?v=EuA9Rt805

You click play button, there are two window opened, current page was reloaded, and then users view counted.

I am wondering They are not afraid of cheating?

It seems they connected with advertisers network for callback url? and then confirm view via callback url?

Thank you very much
