Anything that is not natural sounding language is probably kw stuffing. It used to be ridiculous repetition, but even though it may not look as crazy as that anymore, if it looks strange or weird to you, it's probably stuffing.
The example you gave above is what's called "doorway pages". They are most likely the same (or very similar) page with just a few kw's swapped out. They offer no value other than trying to get ranked.
