Many of us like to disable (IE) or hide (Firefox, Chrome) the Norton Toolbar while still having Norton block webpages.
I find that most websites Norton Safe Web recognizes as having a phishing attack are rated Caution and it is only if you land on that specific page or a page that Norton finds suspicious that Norton will block the website, while if you land on another phishing page of that same website Norton will not block it. (unless Norton finds it suspicious).
