You may add me to the list of people who find the text confusing.
Actually, I would go further than that and say that the text is not
just confusing - it's simply wrong.

To me the update seems like an attempt to rationalize some text in the
original RFC that never made sense in the first place.

So, to summarize, I think the following text in the draft makes
no sense, serves no useful purpose, and should be deleted:

   The DNAME RR causes type NS additional section processing.  This
   refers to action at step 6 of the server algorithm outlined in
   section 3.2.
