Try lowering your Volume Step Length for both volumes - this is a common problem when overlapping volumes that are very dense, and have a high step length. If this doesn't solve the problem, please send me a orbx so that I can try to figure out what's going on.
What's happening is this - the renderer ray marches into one volume, and then the intersection of the volumes, and then the other volume. If the step length (set at 1m in your scene) is too small, say, a little bigger than the volume, then the renderer will actually take 3 smaller steps through the overlapping regions of the volumes. This will actually cause the rendering of the overlapping region to be more accurate - in this case, more dense and therefore darker...
