[Orgmode] something odd with org-remember-mode and kill-ring-save

[Good Bad]

I made a wrapped version of org-remember-kill which saves the remember content 
to the kill ring and then calls the original org-remember-kill.  It works as I 
expect in most cases but not always.

First, the relevant elisp code is:

(define-key global-map "\C-cr" 'org-remember)
(defun org-remember-kill-my ()
  (interactive)
  (unless org-remember-mode
    (error "This does not seem to be a remember buffer for Org-mode"))
  (let ((beg (point-min)) 
        (case-fold-search t))
    (beginning-of-buffer)
    (search-forward-regexp "^* " nil t)
    (setq beg (or (match-end 0) beg))
    (goto-char (point-max))
    (skip-chars-backward " \n\r\t")
    (copy-region-as-kill beg (point))
    )
  (org-remember-kill))
(eval-after-load "org-remember" 
                 '(define-key org-remember-mode-map (kbd "C-c r") 
'org-remember-kill-my))
(eval-after-load "org-remember" 
                 '(define-key org-remember-mode-map (kbd "C-c C-k") 
'org-remember-kill-my))


When I bring up remember window and then writes "one two three" (without 
quotes), and 
kills one word (by pressing <C-backspace>, which calls backward-kill-word) and 
press 
C-c C-k or C-c r (which calls the wrapper org-remember-kill-my, then the saved 
content 
is not "one two ", it's "threeone two". 

The odd thing doesn't happen if I call my wrapper function with M-x, or if I 
move my cursor
after <C-backspace> and before pressing C-c C-k or C-c r.

It's as if the append-next-kill command is being called somewhere. 
How should I fix my wrapper?
