Minecraft wiki entry for Creative, associated text: Some items behave differently in Creative mode. Items do not disappear or lose durability when used. For example, putting an item in an item frame or on an armor stand does not cause it to disappear from the player's hand. Instead, the item is duplicated. It is the same for putting on armor by right-clicking it from the player's hotbar. Also, empty buckets simply makes liquids disappear.
