If you mean that it allows for a different rake upwind and downwind,
that has a correct sound to it.
Yes, when sailing downwind the mast automatically tips forward, the spreaders pivot toward the stern and the force of the stays is thus equalized keeping the mast straight while the boom vang keeps the main sail fully exposed to the wind. When sailing upwind (tacking necessary) the spreaders still maintain the straightness of the mast though one stay will go slack causing the spreader on the taught side to do double duty.
Larger boats utilize a back stay to maintain a mast rake usually with a hydraulic adjustment mechanism..
