Wow!  I'm not even sure what to say about that.  Any form of trouble in the cut and you have no control.  One of the reasons for the "shoe" as you suggest is if you feel pinching, binding, etc while in the cut you can hold the workpiece in place and turn off the saw.  Its never good to run into trouble while in the cut but crap happens and with that pick you have no control.

I would also like to point out he's fiddling about checking his fit of 2 pieces while the saw is still running.  I may operate on the wrong side of paranoid but if I'm not actively pushing stock thru the saw its off.  I don't care if its just for 30 seconds the saw turns off.  This is so I only focus on making the cut and nothing else.  We've heard time and again that accidents mostly happen while tired or when we lose focus.
