Wrapping text in single-backticks doesn't do anything in rest, you have to wrap it in double-backticks, that's why these aren't rendering properly. Also I'd use a definition-list here it's more semantically correct and also looks nicer. So:

    ``ckan.auth.anon_create_dataset``
      allows non registered users to create datasets, default: False
    
    ``ckan.auth.create_dataset_if_not_in_organization``
      users not in organizations can create datasets, default: True

(I know markdown is much nicer) I find the [Quick reStructuredText](http://docutils.sourceforge.net/docs/user/rst/quickref.html) page useful.

Stuff like this is easier to read if each definition follows the same form, so either _"allows non registered users to create datasets"_ and _"allows users not in organizations to create datasets"_, or _"users not in organizations can create datasets"_ and _"non-registered users can create datasets"_ but don't mix both.

Let me know if this is getting far too nit-picky.

"Users not in organizations" is a bit unclear, I think this means "Users who are not members of _any_ organization can still create datasets"? (and then these datasets will not belong to any organization?) It's always good to be explicit.
