Can you "steal" if the last piece lands in the hole it came from?
You are able to steal if the last piece lands in the hole it came from.  

From wikipedia:


  If the last sown seed lands in an empty house owned by the player, and
  the opposite house contains seeds, both the last seed and the opposite
  seeds are captured and placed into the player's store.


In this case, your last stone is landing in an empty hole on your side of the board, and the opponent's hole has stones.  Therefore, you steal those stones.
