Offenses may come up with a 20- or 25-play script to start a game. They add specific formations to see a defense react to it and use a specific motion to see what you are ready for. Really, those first 20 or 25 scripted plays may not have anything to do with down and distance. So, it is more reactive in a sense on offense, to see what the reaction will be.
