Good question, as usual. The idea is that a clone has exactly the same 
settings (except those which are requested to be changed explicitly and 
the disks which are to be handled according to the requested cloning 
variant). This includes the group. At the moment I can't explain why the 
group would be lost...

Just a few days ago we bumped into the question of appliance 
export/import needing group support (especially when there are multiple 
VMs in one appliance), which is closely related.

This is clearly a topic which needs some thought in the API design. At 
the moment I suspect that a lot of operations should but currently 
aren't  group aware. There's actually a lot of group related 
functionality still left on the "todo" list...
