more clarification - click on above link and note in the boxes there are rankings next to each country, for eg. australia its 1 and south africa is 5.. which means that A1 will be australia and A2 will be south africa irrespective of how they finish in the top two of their group. this ranking for the grouping was frozen at the end of the 2005 season and the schedules were drawn up so it becomes easier for cricket followers to visit the many islands of west indies and plan their stay and travel accordingly to avoid chaos in these small countries.
