I'm not sure this can be called a bug. It is true (and perfectly  
normal) that rendering a filesystem page template will always call  
the CPM. You're rendering both here. Since output_page_2 is rendered  
last as it's calles from output_page_1 the rule for output_page_2  
fires and will overwrite existing headers/add new headers according  
to the rule that fires. The problem here is that both happen in the  
same request, the rendering code does not distinguish betwen the  
primary and the nested rendering.
