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

[David Sewell]

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>
