Not a bug. When you get the bounding volume on a geode, the
bounding volume contains the geometry beneath it without any
regard to what lies above it in the scene graph. That's how
hierarchical bounding volumes work. It's really the only way.
Suppose the geode were instanced several times in the scene
graph under different DCSes.
