Anyone else find this 'conviction' suspicious?

Or rather, the first 'confession' obtained from anyone at Gitmo. By an Australian held there for over five years now, only obtained in exchange for a deal that only makes him serve 9 months in prison in his home country of Australia, a deal that was kept secret from the military panel in charge of sentencing so when they handed down a seven year sentence... bam, secret agreement unlocked that limited that sentence to 9 months, he gets to go home.

To be honest, I don't care what another country was trying to convict me of, if I only needed to plead guilty in exchange for going home after being kept under lock and key for half a decade, I'd take that bargain in a heartbeat. So while I'm sure all the news pundits will start trumpeting this as proving Gitmo can be a success and can work... read between the lines, look at how few point out that the only reason this 'conviction' happened is because the sentence-limit of the plea agreement was kept secret from the sentencing panel and because the person was already kept imprisoned for over five years first.
