Yes, but fudging this way answers your dilemma from earlier: the players don't see it. Yes, they see the die rolls, and they can piece together certain information.What does it matter if you fudge or not fudge, though? You're the DM. You control all elements of the game world.
If you see the PCs are getting their butts handed to them and you back off on the number of enemies that they are supposed to fight--2 show up instead of 6--isn't that fudging?
If you roll behind a screen, they don't know what you're rolling, and you can fudge stuff if you want to. That's good for some groups, but I get heavily suspicious as a play if I have 22 hit points total, get dropped to 5 throughout combat, and then enemies start missing me multiple turns in a row. It could be legit, it could be fudged. I don't know. But it does pull me out of immersion. However, if the roll is in the open, that's not the case, because I'm not worried about cheating.
However, if you fudge people showing up, or tactics, the players aren't worried about it, in my experience. Only two bad guys show up? That's fine, they have no idea you fudged the encounter. Nobody worries about you going soft on them, unless they knew there were six guys up ahead, via scouting or something. This type of fudging is softer, and a lot more subtle. It's really the better way to go about it, rather than dice fudging.
So, personally, I'll adjust encounters if I think I overpowered them from their original concept (that is, not if they've overpowering to the characters, necessarily, just too overpowered for what I thought they should be). But I won't do this via die rolls, because that's much, much too overt. I'd rather adjust hit points, attack bonuses, saves bonuses, tactics, mindset, and the like.
Yes, you're the GM, and yes, you control the world, but I find it's a lot better to let players know they've earned every single win they get. And, in my experience (which will vary from others), this has been accomplished by not fudging die rolls, but fudging other stuff when I misjudge it.
Just my thoughts on why it's different. As always, though, play what you like
