No, that's the opposite of the moral of that story. If the person you responded to had listened to the fact that the auto-enter didn't auto-enter, they wouldn't have been at any risk. Likewise in the article, the problem was that the CEO copy-pasted the password into the phishing page's password field, NOT that the auto-enter prompted him to do so.
As I mention below: Autofill doesn't always work for every site. So, now you're having to store in your mind where it works and where it doesn't. By disabling it, it forces you to go the extra step (command-shift-L) every time.
