counter macro doesn't increment when additional macro is on same line

the {{{n}}} macro seems to reset to "1" if it is located on the same line
as another macro that I've defined.  I'm not sure if it's error with my
macro or some kind or race condition-ish problem in macro expansion.
Here's a minimal example:

--------
#+MACRO: ts (eval (get-ts+7))

#+BEGIN_SRC emacs-lisp
  (defun mwp-add-week-to-next-ts ()
    (interactive )
    (save-excursion
      (re-search-forward org-ts-regexp)

      (let ((base (match-string 0)))
        (message base)
        (message (format-time-string "<%Y-%m-%d %a>"
                                     (time-add (date-to-time base)
(days-to-time (1+ 7)))))

        (replace-match (format-time-string "<%Y-%m-%d %a>"
                                           (time-add (date-to-time base)
(seconds-to-time (1+(* 7 60 60 24))))) nil nil nil nil))))
#+END_SRC

(week {{{n(w)}}})

(week {{{n(w)}}})

(week {{{n(w)}}})
