I'm not an expert but as far as I know it can make a difference to the fetus depending on where in the uterus the embryo implants. I guess some spots are not as choice as others. For example if two placentas are attached to the uterus too close together, one may rob another of the nutrients that are needed or placentas may be smaller if they are kind of squashed together.
