The difference is that the invisible guy is in a (relative) infinite area of darkness as opposed to standing in a 3m x 3m patch of it.
The invisible guy can make his position (and presence) sufficiently unknown. The dude standing in a small patch of darkness, cant.
He can be as quiet as he wants, but I wouldnt let him hide in there. No hide action allowed. No need to guess if he's in there or not, and no need to guess his square. He otherwise retains all the advantage of having heavy obscurement though.
Billy the Wizard cant cast Power word kill on him because he cant see him. Frank the Paladin cant make an attack of opportunity on him becuase he cant see him. Grog the Barbarian can run into the darkness swinging his axe like mad and can attack with disadvantage. He doesnt have to 'choose a square' to target. He just runs in there and (assuming the NPC is still in there) rolls his attack.
Ask me the same question in a larger area of darkness and the answer might be different. In that case it might very well be possible to go into hiding (as the combatants move around quietly in the darkness) if the combatants can mask their location with sufficient precision (similar to how an invisible person can).
I guess I sort of understand your reasoning, but it really doesn't seem to line up very well with other pieces of the mechanics and seems to potentially lead to absurd conclusions -- which I know you are not fond of

Or perhaps more to the point, suppose the area is instead 50x50, which seems to be big enough that you would allow the NPC to hide. So presumably Grog now must guess where the NPC is in order to not automatically miss him. However, apparently, Grog can effectively attack a 20x20 area. So does Grog need to guess the 5x5 space that the NPC is in, or does he only need to guess some 20x20 area that the NPC is in? It seems that you run into some consistency issues if you say 5x5 or you're giving Grog a sort of AoE attack if you say 20x20.
