Wow, @Jesse373, very good question. I've never asked them for a copy. Here's what I found - a PDF of the Host Protection Insurance Program Summary. This seems a more complete summary than the one you refer to - possibly? - because there are more specifics about what's covered (see for instance pages 3 through 7).

Also in this document is an email address at Aon, the insurance provider: "Please email airbnbhostprotection@aon.com if you have questions regarding the coverage made available under this program."
I would write to Aon and request a copy of the policy if the above doesn't suffice.
