I think the big improvement would be consistency. Either all servers would be correct or all servers would be incorrect. The step where "Since they were unable to determine what was causing the erroneous orders they reacted by uninstalling the new code from the servers it was deployed to correctly" wouldn't have had a negative impact. They could have even instantly rolled back. Also if they were using the same automated deployment processes for their test environment they might have even caught this in QA.
