yes, though at the edges there can be effects caused by light bending as it passes the edge of something.

have you ever been out under those modern LED grid array lamps and watched what it does to shadows? oh yeah, holes in tree cover, during an eclipse you can look at the image of the eclipse the little holes in the tree create. functions like a lens, but without any brightness loss.

so, yeah, shadows and light bending around stuff as it skates past is something that happens before two shadows overlap and create a darker shadow.
