Most CAD programs I've used store a tree of features/actions used to get to 
the final shape, this means you can go back and edit any of those previous 
steps.  In your example the shape you drew to make the hole is stored 
exactly as that in the file, then of course you can edit it and see the 
result.  I saw partly this kind of behaviour in 3D Studio Max (or whatever 
it's called now), in that you could keep two separate objects and see the 
intersection of them, but most mesh editors just store the mesh and no extra 
data.
