This is done currently using the building's collision mesh bounding radius (actually it seems to be extent/diameter and not radius) and frustum::TestPoint. Tall buildings are not even close to being spherical, so when a tall building disappears off the edge of the screen it is still considered for drawing. Adding a bounding box check to Frustum would be more suitable.
