It depends.
If Obj1 only have a relatively small part removed and Obj2 is relatively 
large, like a large sphere, and Obj1 is comparatively small, it can 
restrict the bounding box back to a more resonable dimention.

It's not realy helpfull if Obj2 is small and simple, or is already 
located totaly inside Obj1's bounding box.
