Sometimes when people ask a question it is sufficiently answered and then people restate the answer like the dufflepuds in Narnia voyage of the dawn treader. Example: http://pokemondb.net/pokebase/31161/can-i-get-a-second-ditto-in-pokemon-white
Most of the answers were posted at the same time, so they wouldn't have seen the other answers as they were writing the question.
The answer that came later from SuperFlygon did add some more information, so that's OK in my opinion.
