"Bowl offs" are the method that was previously used in the event of tied T20 matches, bowlers from each side bowled at unguarded stumps. Kind of crappy way to do it for the crowd so they introduced super-overs.
Their rule is outdated but clearly intended to void wagers if any extra deciding activity takes place after the two innings (bowl-off, toss of coin, super-over, magic eight ball etc) so good service of them to give you the win.
Props (most sixes for e.g.) will exclude super-overs because cricinfo doesn't update the scorecards with stats from Super-overs
