It is so the swipe from bottom gesture doesn’t get impeded. I wish my case for my XS was built that way. Instead I scrape up agains the case edge when swiping. It is less than ideal.
Anyway, There is only a small portion of the bottom that is not protected and the phone will not be hit if the phone falls on a flat surface even with that bottom falling first. I’d gladly take that minimimal extra risk. Frankly, all I really want are the corners to be covered. That is where the phone is going to hit if it falls on the floor.
