Yes, your understanding is correct (I use that for SSH session into my 
remote Linux box). The biggest benefit I got from AutoHotKey is now I 
can use the right Alt key in Putty sessions, since I mapped the right 
Alt key to the left Alt key.
I don't understand why under Putty, a lot of control keys work out of 
box on editors like "nano", but it is so twisted to have them work in 
Emacs. As much as I like Emacs, I think people dreaming in "Emacs is 
(nearly) perfect" need to wake up.

Here is some example key bindings from my emacs config:

--------------
  ;; this is inside my org-mode-hook

  ;; Alternative key binding for putty. basically Meta is replaced with 
C-x, Ctrl is
  ;; replaced with C-c

  ;; for M-up/down/left/right
  (define-key org-mode-map [(control x) up] 'org-metaup)
  (define-key org-mode-map [(control x) down] 'org-metadown)
  (define-key org-mode-map [(control x) left] 'org-metaleft)
  (define-key org-mode-map [(control x) right] 'org-metaright)

  ;; for C-up/down/left/right
  (define-key org-mode-map [(control c) up] 'org-shiftup)
  (define-key org-mode-map [(control c) down] 'org-shiftdown)
  (define-key org-mode-map [(control c) left] 'org-shiftleft)
  (define-key org-mode-map [(control c) right] 'org-shiftright)

  ;; actually, M-return works in putty. So we use "C-x return" to do 
"M-S return"
  (local-unset-key (kbd "C-x RET")) ;; originally bound globally to char 
coding commands
  (define-key org-mode-map (kbd "C-x RET") 'org-insert-todo-heading)

Attached is my AutoHotKey script.
