In the conditional of lines 24-26, and again in 28-30, you're testing for the presence of a hash key, then populating that level as an array. Your Dumper output confirms that the array treatment wins. You don't push onto a hash, you assign. Since you have an array, the hash key never exists and each $policy seen goes into the array, duplicate or not.

Aside from that, I'm unsure what you're asking.
