Does not filter

"After you have configured the module from the settings page, you need to add the "Object and embed" filter to the appropriate input formats (such as "Filtered HTML") on the input formats administration page. Configure your HTML filter to accept , and tags by adding them to the list of accepted tags. Configure the order of the filters so that the "Object and embed tag" filter comes directly after the "HTML" filter. After this you should be ready to go!"

I did so. Ok, now videos are shown - but from every site. I have just "www.youtube.com" to the allowed host list.
I created an article using the "filtered html" added 2 s, 1 from youtube one from an other site. Both are shown. (The second should not be shown since the site isnt an allowed host!)
