With adspeed its a zone and you can place different ads in it, on my video site with the same code there are two ads being served, same with blog but no mobile there yet.
Was unaware of that but just gave it a try
Was hoping to mark solved but no go, however, I am now getting browsers to identify the attempt
so that got me closer 
this means something simple to you?
