The instructions are based upon when the hops are added and how long they remain in contact with the beer. Both of these are set by the user when adding the dry hop step to the recipe in the design box. In your case, the instructions now state to add the dry hops 3 days before you bottle the beer (the when) and allow them to remain in contact for 14 days (the duration). Obviously this is not how you want to do it, so you can and should adjust these times in your recipe.
