The comment was not accurate because of the break. Well, I guess it could also mean that the cases above all fall through, but I think most people already understand that and it doesn't need to be commented about. I also found this comment a bit confusing given the break (maybe there's somehow something special about the break that means that it actually falls through?) so I think it's best to delete it.
