Andy, This works because the action on the "Postmaster" test is ROUTETO back to the postmaster.
How it works [1] Lowers the weight of the email by 100 so that the message will not be held or deleted in our system [2] Re-routes the message back to the postmaster only if the postmaster account was an actual recipient of that email. Our policy is that we want to accept any mail destined to the postmaster or abuse account simply because if someone is being blocked by our spam filtering we would like to give them the opportunity to contact us to resolve the issue. However, with just whitelisting the postmaster account you open yourself up to allowing spam to your users if the spammer adds the postmaster account to the email. The solution above mitigates this, because it reroutes the message to the postmaster preventing it from going to the user. The -100 just prevents it from being deleted. So in the end [1] The postmaster gets the mail and the other recipients don't.
