I was trying to avoid confusion. <@ is the "contained by" operator
which is also returning true when both sides are equal. We shouldn't
continue calling <<@ also "contained by". I removed the "(subnet)"
and "(supernet)" additions. Can you think of any better wording?

I copied that note from the Geometric Functions and Operators page.

You are right. I reverted that part.

Thank you for the review. New version is attached.
