We use "as well as" to mean "and in addition", "and also", but the following sentence completely made me confused:

> [There are roughly 1000 different words for “water,” as well as for “louse”.](http://www.sciencemag.org/news/2015/10/one-thousand-different-words-water)

I know that above mentioned sentence should mean that "there are roughly 1000 different words for “water,” **and also** for “louse”.

Doesn't that mean that there are individually 1000 words for “water” and another 1000 words for “louse”? If so, then we have 2000 words. Please correct me if I am asking wrong.
