Because Multi is also a Field-element, when you add a constraint to
it, it doesn't get added to its children, unlike with other Block
elements.
If you add the constraint to one of the "country" fields, it should work.

On a side note - the recent threads about the Multi have made me
realise it needs looking at a bit more closely - I think we probably
also need a complimentary Block element that will provide the same
kind of layout as a Multi, but without the confusing differences that
a Multi has.
