footnote.el seems broken in this regard:

(1) Setting `footnote-section-tag' without simultaneously setting
    `footnote-section-regexp' to a value matching `footnote-section-tag'
    like you did will give unpredictable results.  Probably the option
    `footnote-section-regexp' should be removed and `regexp-quote' used
    instead.

(2) You can't set `footnote-section-regexp' to match the empty string,
    it will always match at eob even when there are footnotes before it.
    A separate value would be needed to indicate that a user doesn't
    want to set a section tag.

(3) If you don't set a section tag you can't reliably use
    `Footnote-narrow-to-footnotes' since this is searching for a section
    tag.  Also `Footnote-delete-footnote' might fail when all footnotes
    have been removed :-(
