Well, explaining to people in words what they already can see with their own eyes seems a bit patronizing and redundant to me. Every Interactive Diagram can be used to see how pieces move differently from in orthodox Chess. This Diagram is not any different in that respect. It is just that the optimal placement of pieces to show their moves needs not be the same for every type of move, even though for the large majority central placement is best. It can be expected from the creator of such move diagrams that he made his best effort to provide a good one, in that respect. Why elaborate on the obvious?
