I see it more of a performance tweak than a relevance thing. matches on stopwords introduce the potential for many more documents to be scored.
Large collections usually should have a high min-should-match, so more than likely queries with at least one or two non-stopwords that dramatically limit the docs that will be scored. And since large collections are where people have stopwords perf problems, this tends to obviate the performance gains of removing stopwords.
