This happens because with point at the start of the "1970." line,
forward-paragraph skip to after "test". This does not happen in
text-mode. It happens in mail-mode because the "1970." line happens to
match paragraph-separate, specifically the element:

(?[0-9]+[.)]+$

Off the top of my head, I don't know what this element is supposed to be
for. It seems to have been added by you in 1998:

http://cvs.savannah.gnu.org/viewvc/emacs/lisp/mail/sendmail.el?root=emacs&r1=1.199&r2=1.200&pathrev=MAIN

1998-07-24  Richard Stallman  <rms AT psilocin.ai.mit.edu>

    * mail/sendmail.el (mail-mode): Add the citation regexp
    to adaptive-fill-regexp after the usual contents.
    But modify the usual contents not to match whitespace alone;
    match that again last.
    Add that citation regexp to paragraph-start and
    paragraph-separate too.

(Message mode does not have such an element.)

This is an old element from adaptive-fill-regexp that attempted to fill
numbered lists, I guess. You removed it adaptive-fill-regexp in 2006.

2006-09-08  Richard Stallman  <rms at gnu.org>

   * textmodes/fill.el (adaptive-fill-regexp): Don't match `(1)' or `1.'

Obviously mail-mode's setting of paragraph-separate hasn't kept up;
it should be simplified.
