He gives the distance-2 graph of the Gosset graph, and not a description of the gosset graph itself. The alternative construction comes from looking at the vectors and letting {i, j} be the index of the 3s and the chosen K_8 being the sign of the 3. Then it becomes obvious that these two are identical. Another way to see that original description by Haemers is wrong is to take 2 points distance 2 and find all points adjacent to both. There should be 10.
