Ok, this is how --wrt-author sorts your example:

(Original example transposed so that variable width fonts don't play
havoc with the layout)

a10 b9
| \  |
a9  b8
|    |
a8  b7
|    | 
a7  b6
| /  |
a6  b5
| \  |
a5  b4
|    |
a4  b3
| \  |
a3  b2
|    |
a2  b1
| /
a1

with respect to a and b respectively

A         B

| b9      | b9
^ a10     ^ a10
| b8      | a9
| b7      | a8          
| b6      | a7
| b5      ^ b8
^ a9      | b7
| a8      | b6
| a7      | a6
| a6      | a5
| b4      | a4
| b3      | a3
^ a5      | a2
| a4      ^ b5
| b2      | b4
| b1      | b3
^ a3      | b2
| a2      | b1
= a1      = a1

In otherwords, B doesn't see any of A's changes after a1 until b6,
whereas A sees some of B's changes at a4 and some at a6, then not
again until a10.
