You wouldn't think that for a few reasons. First of all, sumwun is a good user who, as far as I know, wouldn't even think about taking somebody's answer and reposing it. Second of all, Bulbapedia is by far the most popular place to look first for an answer to a question. It's not unlikely that, when a question is simple and easily answered, two answers both use the same source and quote the same sentence that answers the question.
