After posting I've just watched the video. In the simulator engine failures at very low speed like this often end up with the same result you see here. The reason I'm told is because pilots are generally not expecting it then, they are waiting for the problem to occur at high speed and they don't react quickly enough to retard the thrust levers. It is more challenging than most of us would have thought.
That information is second hand as I am not a sim instructor, I was told it by one.
