The difference between case 1 and cases 2-4 are that in 1 the client is letting the server expand the group membership, and in 2-4 it's the client doing that expansion.  The group members returned by the server when it expands the group are "guaranteed" to work because the server definitely knows about them (and providing them to the client).  In the cases where it's the client adding the attendees, I suppose there must be some mismatch sometimes, although I don't know what that could be if the email addresses are the same between the users you've created via Contacts.app and the users you've created via Server.app.
I actually tried this setup and it was working fine.  What caused you to want to duplicate the users and groups that you have in Server.app into Contacts.app?
