There seems to be a problem in this 9.4 JSON doc paragraph in json.sgml:

    The technical difference between a <literal>jsonb_ops</literal>
    and a <literal>jsonb_path_ops</literal> GIN index is that the former
    creates independent index items for each key and value in the data,
    while the latter creates index items only for each value in the
    data.<footnote><para>For this purpose, the term <quote>value</>
    includes array elements, though JSON terminology sometimes considers
    array elements distinct from values within objects.</para></footnote>
--> But in <literal>jsonb_path_ops</literal>, each index item is a hash
    of both the value and the key(s) leading to it; for example to index
    <literal>{"foo": {"bar": "baz"}}</literal>, a single index item would
    be created incorporating all three of <literal>foo</>, <literal>bar</>,

What does this "But" refer to, and it is consistent with the sentences above?
