It's ajaxSingle="true" that helps you run your code without following recommendations.
In my view a:outputPanel optimizes the AJAX requiest since:

Reference:

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.
