@MyFavoriteChanneI He is saying that the product will act on the surface of your teeth, “corroding” the natural finish of the teeth and leaving it more likely to stain. After two weeks your teeth will have completely recovered the external layer, and it will not get so easily stained. It will still be “whiter”
