In case this might be useful to anyone, I’ve improved this somewhat to 
handle better the case where point is mid-word:

#+begin_src emacs-lisp
(defun my/electric-quote-inhibit-pair (orig-fun &rest args)
 (if (and
      (not (eq (char-syntax (preceding-char)) ?w)); no word char before 
      point
      (eq (char-syntax (following-char)) ?w)); word char after point
     ;; If at the beginning of a word
     (progn
       (apply orig-fun args)
       (pcase electric-quote-chars
         (`(,q< ,q> ,q<< ,q>>)
          (save-excursion
            (cond ((search-backward (string q>) (1- (point)) t)
                   (replace-match ""))
                  ((search-backward (string q>>) (1- (point)) t)
                   (replace-match "")))))))
   ;; Else do as usual
   (apply orig-fun args)))

(advice-add 'electric-quote-post-self-insert-function
           :around #'my/electric-quote-inhibit-pair)
#+end_src


Best regards,
Gustavo.
