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.
https://github.com/bigscience-workshop/data-preparation/blob/9d0588419073cc5bf0fb92b58f37f2a1016572c3/preprocessing/training/01b_oscar_cleaning_and_filtering/filtering.py#L590
But in [notebook](https://drive.google.com/file/d/1cCJ8sWE88TRLDAa3eHLmXO4JlkR2QzLY/view), 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!
