Here's an extract of the clusters it inferred, headed by the most commonly occurring element of the cluster in my corpus (corpus = arbitrarily selected project gutenberg ebook, apparently about whaling)

I like how it nailed prepositions pretty well (and in fact and, or, but were off their own cluster earlier in the iteration, before they merged in) and modal verbs all landed together, and a lot of numbers ended nicely in the same bucket as determiners.
