By elevating head-to-head results (rule i) above points difference (rule ii), a notable difference is created to other sports competitions, in which points difference usually determines rank for teams with the same number of match points (table points). These rules allowed the winners of Pools A, B and C to be determined by the results of the third pool matches on the weekend of 22 and 23 September. Although other teams could theoretically draw level on table points with South Africa, Australia and New Zealand and exceed their points differences at the end of the pool stages, head-to-head results by that time ensured these teams could be declared winners of their respective pools, with a match to spare. This also illustrates the fact that the pool tables do not tell the whole story.
