You're not reading enough into it. They mean allow you to save at any time, anywhere. Like if you're doing this quest and your last save point was 30 minutes ago, and you're about to finish the quest to open a door to some boss which will allow you to save, but you have to go to bed, or eat dinner, or let your parents watch TV, or whatever. To save then so you don't have to leave the console on paused for 30 minutes, an hour, overnight, etc.
