The thing about the Clark/Superman nobody-sees-through-the-disguise-thing is, we, the audience, know it, of course. But why would anyone in-universe think Superman had a secret identity? He's not wearing a mask.
And so, that journalist with the glasses looks a lot like Superman. But could it be him? Seriously, though, why would Superman, of all people, work at a newspaper. That's like, I don't know, seeing someone who looks like Matt Damon working in an office. Yeah, he looks like him, but there's no way. Maybe some even think about it enough to tell him "Hey, you know, you look a lot like Matt Damon", but he just says: "Yeah, I get that a lot. Even thought about doing some look-alike appearances, but I got little enough leisure time as it is."
