I'm not sure I'm understanding this properly. Here's how I tried to test 
this:

  1) import this entire series with parsearchive.py
  2) took this patch, and updated its headers to:
     - have a new "Message-Id"
     - make In-Reply-To and References point to the original 10/10 patch.

  3) imported this new hand-crafted patch

The result was the new patch being added to the same series revision. 
The way I read this commit message, I was expecting it to generate a new 
SeriesRevision. Am I missing something?
