It's ajaxSingle="true" that helps you run your code without following recommendations.
In my view a:outputPanel optimizes the AJAX requiest since:
anonymous wrote : The component is used for components grouping in the AJAX output area, which offers several additional output opportunities such as inserting of non-present in tree components, saving of transient elements after AJAX request and some others.
What you do with ajaxSingle is that you submit only the changes to the combo box. I'm actually amazed that A4J manages to update the page correctly. I guess though that it updates the whole page while with a:outputPanel you can update only the second combo box.
