It seems that u have not understood yet ashwin, if bermuda qualifies instead of lanka, then bermuda will be 1 and india will be 2. even though india has a higher ranking.
If the top 2 ranked teams finish @ the top then then irrespective of who is on top the they will be seeded according to their ranks.
If there is an upset and one non top 2 team qualifies then it will take the place of the top team that failed to qualify, as in the bermuda example.
if there is a double upset then the two qualifying teams will be again seeded according to the rankings.
for eg if india and lanka qualify then india is 2 and lanka 1 if india and bermuda qualify then bermuda is 1 and india 2 if india and bangladesh qualify then bangladesh is 1 and india 2 if lanka and bermuda qualify then bermuda is 2 and lanka 1 if lanka and bangladesh qualify then bangladesh is 2 and lanka 1 if bermuda and bangladesh qualify then bangladesh is 1 and bermuda 2
