That was my first impression, yeah. What the actual value of that relative improvement in believability is, I can't say.
Let me elaborate by way of example.
The Bohemian samples up an down bows separately, and the Performer understands (usually) during a phrase which direction the bow must go next. (This can be overridden by keyswitches, but out of the box it works pretty well.)
JBV isn't quite so clever, and doesn't have separate samples for up/down bows (at least not in a way that can be controlled like on the Bohemian), but its randomness/humanization functions still sound pretty convincing to me, even if perhaps they are less correct than the Bohemian (?). Maybe someone more familiar with phrasing on string instruments will more clearly hear the difference, but to my ears the most important aspect is variation and smooth transitions, which JBV does pretty well. A violinist might be able to immediately spot the sound of two adjacent full down bows and call shenanigans, but I'm not quite there myself.
I think the very fact that we're talking about these details is an indication of how far solo violin VIs have come in the past couple years.
