In the second position, the second detent keeps the brake from the ratcheted wheels. The distance of the ratchets from the axle is longer than the distance of the second edges from the axle. Thus, the second detent frictionally contacts the ratcheted wheels in the second position, thus slowing the reeling in of the strap.
