set camera at custom WB taking reading, aim at the main light, fire, than camera records.
you aim camera with expodisc at the main light, is the same like aiming the camera without expodisc at a graycard lighted by the main light.
at outdoor with flash, you still need to aim the expodisc to the flash, or aim at a flash bounce-able area.
the WB will be neutral, but doesn't mean all skintone will be nice.
