It all depends...with this type of flooring, it isn't as durable as say a tiled floor. The likelyhood is that you'll probably end up changing it out before you change the cabinets, so it would be easier to change if it didn't go underneath. Places like under the stove, though might be a good thing to finish - spills are less likely to soak in and the toekick of a new one may not be in exactly the same place.
The cost of the stuff probably isn't that much, so you can if you want to, then you have the potential of moving things or changing things around. But, the stuff underneath won't be subject to fading or other wear, so it may just show anyways. Getting the stuff to lay flat at the joint by the toekick could be a problem, but it depends.
So, I haven't answered your question...basicaly, you can do it either way.
