Here we have a point 'A' and an observer (also called 'A') and a coordinates system called 'K'. The best and most natural setting would be, that you place the coordinate system with its center at 'A' and also the observer in K there. Since the coordinate system k is equivalent in function and settings, we should place 'B' in the center of k. This is simply the best way to place all the items mentioned into a useful order. If you (or Einstein) like something else, this would be allowed, but you had to say so. .... TH
