I don't buy the story. If the force of the "tail end swing", which occurs while turning, traveling forks first direction, is strong enough to eject the operator, then it would probably tip over the truck as well.

What really happened: The operator was traveling (too fast) power unit first direction, realized he was about to collide with rack, jumped out, and was trapped between truck and rack.

Faced with the choice of blaming it on equipment error (don't let facts sabatoge a good story), or admittting to an act of excessive carelessness/stupidity, the operator chose the former.

Any witnesses?
