It has to be a misinterpretation, I don't see why they would do that move, it doesn't make any sense. If he's actually been DFA'd, I wouldn't be surprised if he spites the Jays by throwing a win of relief for someone else, a la Carpenter and Farquhar.
I'm actually upset about this move, but it's less so because I think he might have actually been an asset, and more so because you're just playing around with a guy's career for no reason, and probably pissing off the Bisons to boot.
