risking a Whoosh....& Im not 100% on this, but the super over scenario, I think(?) , as to who bats first ( in the super over shoot out) is a reversal of which team batted first in the 50 overs apiece contest.... it was explained , sort of, in between the 2x 50 overs sessions ending in a draw and the super overs shoot out commencing, by the commentators.... who were probably as aux fait with how super overs work as just about everyone else, apart from presumably ICC or match officials ensuring said commentators had the super overs rules on a print out handed to them after the 50 overs contest was drawn
