In the paragraph starting with "The term...", there is a phrase "for ambient,

22 July 2005, page 157.
One of the constraints on a second printing is avoiding changes that would
cause massive repagination of the book. One change that would have caused
that was not submitted, a clarification to some text in the book. I am
listing it here separately.
A clarification of "All that matters is that the objects represented
by the child nodes are contained in the world bound." A parent node's
world bounding volume need only contain the objects represented by its
child nodes. The following figure illustrates
Even though the parent world bound does not contain the child world bounds,
it does contain the child objects. It is possible that a child world bound
intersects the view frustum, so by itself the child subtree would not be
culled, but the parent world bound does not intersect the view frustum and
the parent subtree is culled. The parent is visited before the child, so
the culling will occur!
