I don't understand. They already sold Worldwide exclusive rights to the Amiga name to Commodore U.S.A. How can they be selling them again? "Exclusive" being what it is, they can't actually sell the name to anyone else or they'd be in breach of contract, surely?
Although, given prior history I don't suppose a minor thing like agreeing a contract and then breaking it a few weeks later is anything that they would be bothered with. However it would be a disincentive to any prospective purchaser. It'd be like buying a house then arriving at the door with all your furniture and finding someone else living there claiming they bought it too.
