header: Inherit exposed form filters

Hi everyone!
Maybe my question was not good enough.

Once again I want to show you my problem: I have got a view with Nodes and an exposed form which is placed in the sidebar.

I wanted to achieve the following: The first node which is shown, should be themed differently - so the surrounding divs and the image style itself have to be altered.
My approach was now to add a child view with only showing 1 element and embed this into my parent view in the header section. Also the right offset etc. is set for both views.

My problem is now, that the exposed form doesn't have any effects to the child view. But why? Do I have to set another option? Is there a better way to alter only the first element of a view?

Greetings
