Membership expiry v's listing expiry: discepancy?

I’m in the process of moving an existing site to PP Directory Theme and have started moving clients data across.

I have listing and membership packages setup, both of which are set to 365 days. I’ll illustrate what I’ve noticed is happening via an example:

* membership package is purchased 1/10/14, hence expiring 365 days later on 30/9/15
* listing is created 15 days later on 15/10/14. The expiry date is quoted as 365 days later on 14/10/15

You can see here though that the listing is supposedly going to expire after the membership expires which aside from making no sense, is just going to confuse everyone. I haven’t run a test to see if this actually happens, or if the listing will expire in line with the membership.

Does anyone know?
