For the visual patterns on the map that does not make a major difference. * Obviously for all of the same color it makes no difference * For all 4 of different colors the pattern still does not change, it's just randomly colored * In case of 2 colors it's highly likely that the first half will have one color and the second one another. Nothing changes. * In the less likely case the 3 have one color and the remaining one is different the resulting pattern is a triangle. So the direction of the diagonal will flip. But I don't think the overall impression will change. In higher level squares replace "color" by "pattern", still no significant changes in appearance. Of course the two lower squares always swap their location.
