You are quite right, he was lucky.Thanks if it comes down to that I'll send you a pm. As for the high lift i'm trying to stay away from those. My buddy managed to destroy mine the other day even after I told him that it was only rated for 4600 and the front end is over 5000lbs. He is lucky he didn't get hurt.
You are also right it was overloaded.
However, using 2 jacks, one on each side of the bumper is safe as long as you keep the load more or less balanced between them which is not really to difficult.
FYI:
