you want to sum them together, if you got 3 lights you see three shadows, the darkest place is where the shadows intersect. are you using point light? the stronger the light the more power the object is blocking, so if you mean it will make a darker shadow this is somewhat correct, not necessarily tho, it could be that the large light is contributing to most of the inderect illumination as well. the physics of why shadows don't look completely black is simply the ambiant light component. it models light with twe or more bounces that is incident on the surface. light with one bounce is taken care of via the local illumination model(light->surface->eye) light->surface*->eye is taken care by the fake ambient term. I'm not quite understanding your method can you explain in more detail?
