Nudity in Transition???

Hi I've recently finished a sprint tri, and a lady (don't know if she was an official or not) came over to me and told me that having my tri suit zip undone (it only comes down to my sternum) was considered nudity in transition, and I could potentially be dq'd ( i wasn't). She also said it was unfair to the females as they couldn't have their zips undone aswell. So I contacted the organiser and they said it was nudity in transition and that the zip should be done up at all times!!!
Is this...
