I think Oliver's point is that the current wording says that the items in a
group always have the same key value, but it doesn't explicitly say that items
in different groups always have different key values. So given three items with
values (1,1,1) you could satisfy the letter of the law by creating three
groups.

(The edge case of non-transitivity needs to be dealt with at the same time.)
