Not at all; if the primary contact were in multiple groups, so would  
the metacontact be. One could also render the metacontact in all  
groups of member contacts.

This is slightly confusing; each jid is only in the roster once,  
although they could be in many groups. Groups are a property of a  
contact, not contacts a property of a group. There are no 'buddy list  
copies', so I'm not sure this is an issue.
