Does CC14 offer downgrade rights

I am a licensing specialist and I am trying to find out if CC14 offers downgrade rights meaning if you buy a CC14 subscription but use an older version of creative suite under this license. I can see that the users dashboard offers the possiblity to download version CS6 but when I read the manual how to install it says the following:

From your Adobe Creative Cloud application, you can install an earlier version of Adobe’s applications (assuming you have a license that is registered using the same Adobe ID), in addition to the CC versions. To do it, make sure you have the latest version of the Creative Cloud app itself. At the top of the window showing the applications you can install you’ll see a dropdown labeled Filters. Simply choose “Previous Version” (pictured below) and — if your previous version is registered to the same Adobe account as you are using for the Creative Cloud — you’ll see the option to install the earlier version of the application.

This suggests that if you want to download CS 6 from the Creative Cloud download portal, you actually need a license for CS 6 that is registered to the same user ID as your subscription. The question is can I use CS6 instead off CC 14 under a CC14 subscription that is registered in my name? And a second question I have is, is it possible to use even older versions with a CC14 license? e.g. CS5 or CS5.5.

I really cannot find any decent information on downgrade rights.

Thanks a lot!
