The question is 'how much' thrust reverse you put in. Certainly some aircraft have engines slung so far off centerline that controlling asymmetrical thrust is an issue, reverse or otherwise.
Honestly I can't think that the Piaggio accident was anything but pilot error...given the engines are slung in back, close to centerline, much like a jet...and certainly if the gear design/asymmetrical thrust combination is so far out of whack, then the pilot should have just applied brakes and forgone reverser usage.
How you flip a plane is beyond me, so want to see the video.
