I'd guess it's similar to using a lot of English words to make compound nouns, except it is slightly worse to read, so if the word is new you'd usually slow down a bit to properly parse it. On the upside, you don't have to guess where the compound noun ends end the rest of the sentence starts, which can also cost time or cost confusion.
