I guess you would really have to fly planes with thrust reverseres to understand my comment.
I've seen pilots pull on reverse and get it wrong. Engines never come up at the same rate, sometimes the rigging is wrong on the reverse levers. And you develop a touch. A touch for the type and for the particular plane.
The flight in question had assymetric reverse and it seems to have pulled the plane to one side. Had they altered that they might have been able to pull the plane back towards centerline.
Directional control with aerodynamic or nosewheel steering is preferred, but if you are going off the side, wouldn't you try assymetric thrust?
