Use Augeas to change kernel audit param fails with multiple title blocks

Question

This example is supposed to change the kernel line in every title block by adding or setting the audit parameter to 1. It works fine if there is only one title block but if there is more than one it doesn't do anything. Am I missing something?

The docs for Puppet Augeas imply that set only sets the value for a single key. There is a setm command for changing multiple nodes.
