BEagle,
Not quite. The incident you are referring to went more like this.
A320 Downroute with Computer fault. Captain "knows" how to reset, but it involved putting thrust levers into a mid power position. Computer reset in E & E bay, thrust levers left where they are.
Following Right engine start on pushback, engine continues accelerating to thrust lever selected power setting. Side load shears towbar and engine ends up embedded in tow truck, with very frightened driver having just got out in time.
