Going by the results it does not look like any groups were disqualfied for breaking the rules and not staying together as a group - unless I have missed the 'disqualified' words against their name.

I think it would be useful for the organisers to publish an account of their investigation as it would be a lesson to others and it would aid understanding of the situation and the RO position / thinking. Perhaps this will happen in time to come. It is in every potential competitors interest.
