You would think, but in practice, they're very good at regenerating. That's why these, and others like oriental bittersweet and Virgina creeper are so problematic. (I don't know if they're strictly in the same category, but they behave the same.)
Dang, maybe I’ll look up their growth process then, I wonder if they get enough energy from the soil, or if it starts storing energy by the time you see the shoots.
Natures fascinating.
So I did a little reading. For rhizomatic plants, the horizontal vine is actually the stem. It's basically one big plant growing horizontally underground. That's why if you don't pull it all, you're just plucking shoots off the stem. And like most plants, if you cut up the stem and plant it, each section will grow a new plant.
Of course, if you completely shred it into very fine pieces, it won't be able to regrow. But it can come back from fairly small ones. You might think you've gotten it all, but it's just regrowing until it erupts again.
