A question about the definition of adjacent edges in 4.2.5.

The following definitions refer to the block-stacking-constraints.gif
image.  (Wouldn't it be useful to have numbered figures?  Wouldn't it be
useful to have an index?)

Adjacent Edges with Block-stacking
When A and B have a block-stacking constraint, the adjacent edges of A
and B are an ordered pair recursively defined as:
    * In case 1, the before-edge of the content-rectangle of A and the
before-edge of the allocation-rectangle of B.
    * In case 2, the after-edge of the content-rectangle of A and the
after-edge of the allocation-rectangle of B.

I don't have much of a grasp of this section, but shouldn't case 2 read:
    * In case 2, the after-edge of the allocation-rectangle of A and the
after-edge of the content-rectangle of B?

I.e., for contained areas, the appropriate relationship is between the
content-rectangle of the containing area, and the allocation-rectangle
of the contained area?
