A too high shutterspeed will not give you underexposure, but will partially not expose the negative at all, because during the flash the shutter is obscuring the negative partially. The part of the negative that is exposed however should still show a correct exposure. Whether the non exposed area is an horizontal or vertical one, depends on the movement direction of the shutter. Newer ones will move in vertical direction, leaving a horizontal area unexposed if set at a too high speed.
