Odd statement from that link..

"Seat belt forces were lower for all occupants in the aware condition,
indicating that their internal musculature altered their subsequent
forward rebound motion."

There is a better alternative theory for that.. when the brakes are on
there is less forward acceleration of the van and hence less force on
the passengers to create the rebound.

Any statement on here involving physics/mechanics is immediately
suspect.
