Perhaps it does because you have seen the icons already so even if they're not there, you have no trouble "matching the right icon to the right line of text". Thing is, above it is promised you will find a list of all the icons, but you won't. Perhaps others who are unfamiliar with these icons are looking for something icon-looking. We still get questions about that NO 90, but if that piece of text was acompanied by the NO GO icon, then perhaps their light bulb would light up before asking "what's wrong with the number 90?".
