Huh, very strange, I think it may be one of those 'everybody knows that' rules that maybe was explicitly stated in a previous edition. I can't find enough to make an argument I'd really want to stand behind in either direction. Based only on the KB rule and the CR rules, I'd be inclined to say it only counts as one wound.
