The FO has to reach over the throttles in order to reach the speed brake handle. Not only is it possible to interfere with auto-throttle movement, it's very easy to do and HAS HAPPENED numerous times before...
Usually the FO says, "Oops. Did I do that?"
After BA, they say, "Argh! Engine Failure! Engine Failure!"
