updated pages not appearing in queue?

I just made a couple of (what I hope are) clarifying changes to the  
diff and patch area of the handbook.
The new background page I added (http://drupal.org/node/70745) shows  
up in the queue, which is great.
However, my change to another page (http://drupal.org/diffandpatch)  
has all but disappeared.
I didn't expect my changes to appear immediately -- I find  
reassurance knowing others will check my work before publication --  
but the changed page is not showing on the Handbook Updates page  
http://drupal.org/handbook/updates, nor in the jumbled moderation  
queue http://drupal.org/moderation-queue.
Did my page revisions get lost? Or is the new version not tracked on  
the updates page?
