Does increasing your vocabulary mean you can write longer sentences or write more lively sentences or spend less time on revisions or be able to spend more time reading?
To get all those benefits you also need to know how and when to use the new words you learn. Many may only be used to certain types of language. For example, some may be formal, others colloquial and so on. Incidentally, writing long sentences is not necessarily a virtue. Always aim for pristine clarity.
