Have you seen the video of the Iraqi insurgent firing the mortar, and then being blown up?

The video is accompanied by information that claims the insurgent is killed by return mortar fire that is triangulated to his exact location by new "Mortar Tracking Technology". If such things exist I think that is awesome. I even think it is possible, however in the video it appears to me that the 4th mortar round misfires killing the insurgent. Am I wrong?
