You clearly don't have a clue about how bitcoin works. If two parties want to make their transactions totally untraceable it is possible. As far as I can tell, this transfer could be made by the same wallet, from generated address to the other in order to initiate speculations and show that BTC can actually be used for big un-taxed, non-stoppable money transfer, or it was just a way to show to the IRS what money is missing by not endorsing bitcoin asap.
