I was not understanding how it works, this is what AlexT wrote..
1. Page access control is working without any problems all the time, if it doesn't work for you check permalinks settings, when permalinks are enabled - one uls are used, when disabled - there are another urls.
2. Menus & Page Block access control - don't work for guests (as you see there are no 'Non-Member' membership group there), because it can be controlled from default menu and page blocks builders.
3. However one problem was found (not mentioned here) - Ticket #2741
