Why stopwords_min_cutoff rather than stopwords_max_cutoff?

Thanks for your helpful codebase!

I am a bit confused about stop words filtering.
The release code removes the document, if its stop words ratio below the certain cutoff.

Line 590 in 9d05884

cond = stopwords_ratio >= stopwords_min_cutoff

But in notebook, section 2.5 states If the stop words ratio for a document is higher than a certain cutoff, it is removed.

I am wondering which one is more useful in your practice.
Thanks in advance!
