faster version in case the TrajectoryState on the surface of the Det is already available.

The first TrajectoryStateOnSurface is on the surface of this Det, and the second TrajectoryStateOnSurface is the statrting state, usually not on the surface of this Det. The stateOnThisDet should the result of
prop.propagate( startingState, this->surface())
