That's not quite true, because there's only a limited amount of time available for transmission. Think of it as having two 56k modems and only one hour to send as much data as you possibly can. If you send the same data on both modems, your chances of getting all data correct are improved. But you can alternatively send different data on each channel, which will let you send double the amount of data if you don't mind the risk of loosing some parts. Even though it went wrong, the *chance* of getting twice as much return data as expected outweighs the loss of single sets of results.
