First of all, many small to midsize biz jets use a similar style of trigger that needs activating to get over shut off gate, so thats normal. I would say we are back in the realm of finding out if RHS pilot was PF as then the accidental catching of both triggers (that need lifting) on PM arm as he reaches around to select full flaps at same time PF comes back on throttle levers.. hey presto you can now shut both down. Next thing is frantically trying to lift back into idle position again in seconds prior to crash. (As indicated by prelim report). Also flying from the RHS is fairly normal too in bizjet world to maintain practice of flying in both seats.
