Because the tactics have changed such that "control" becomes a very nebulous term. Kind of like what this guy said

People like to accuse Russia of using "meat assaults", which is not entirely false, but also not entirely true. During Bakhmut Prigo was actually sending human waves, but those were literal ex-convicts for the most part. Now Russia relies on infiltration tactics. They send a few guys to the grey zone, they sneak around, then hunker down in some place they won't get droned. Repeat until you have a few hundred guys in an area, then move in to occupy the land. Repeat. This is a painfully slow and costly process, but it's the best counter Russia has available to Ukrainian drone spam.
This leads to the concept of "controlling" land becoming a bit outdated. If Russia sends 30 guys into a forest, and the guys are all bunkered down in ditches, but Ukraine does the same, who controls the land? It's hard to say. And you can't trust either side, because they both have political incentive to lie or exaggerate what areas they control. And a lot of the time they don't even know for sure.
It's very interesting to see warfare fall into the trend of post-modernity
