I almost agree with you, but I think it actually does bring you much closer to resolution.
The reason is that by default the rhetoric and content, (as you've put it) are deeply conflated in the minds of the people who are engaged in conflict. NVC can tease them apart, and often the content that is left is literally nothing (ie. it was all just a matter of feeling respected or whatever), or a trivial disagreement that can be quickly solved.
But even when the conflict turns out to be non trivial, NVC is a boon. If all parties to the conflict are now in a non violent frame, then what has happened is the problem is quite clear, the stakes for everyone involved are quite clear, and all the people are in a collaboration together to figure out a solution that addresses what matters.
So you're right that it doesn't automatically solve any specific, objective problem, but it sets up the environment so success becomes way more likely.
