[MarkLogic Dev General] Behavior of cts:and-query() with 'ordered'option??

[Aaron Redalen]

The "ordered" option in your example specifies that hits need to occur
in the order of the sequence of queries passed to cts:and-query. 

So in this case, the and-query is only satisfied if the match on "cat"
occurs before the match on "dog".

The API documentation for cts:and-query()

 http://xqzone.com/pubs/3.2/apidocs/cts-query.html#and-query

is confusing in its explanation of the effect of the "ordered" option.
Can anyone explain the logic behind the following differences in output
between the default "unordered" and "ordered" options?

QUERY:

  xdmp:document-insert(
    "/test/test.xml",
    <doc>
      <p>dog cat</p>
      <p>dog frog</p>
      <p>cat dog</p>
    </doc>
  );

  cts:search(
    doc("/test/test.xml")//p,
    cts:and-query(
      ("cat", "dog"),
      "unordered"    (: default option :)
    )
  )

OUTPUT (as expected):

  <p>dog cat</p>
  <p>cat dog</p>

But with the option changed to "ordered",

OUTPUT (why?):

  <p>cat dog</p>
