Distribution of discordant pairs associated with a breakpoint. For each breakpoint, associated discordant pairs are distributed in a belt extended in the diagonal direction (at an angle of 45 degrees) located in the anti-diagonal direction (at an angle of 135 degrees) from the breakpoint. This corresponds to one of the four different conditions on the ordering of coordinates; namely, x i < x0 < y0 < y i for 1 ≤ i ≤ p. As for three remaining conditions, relative positions of the associated discordant pairs are rotated 90, 180, or 270 degrees around the breakpoint.
