I think you mean page 24 (of the release notes), under the section "Where to get more information about Symantec Endpoint Protection, Symantec Endpoint Protection Small Business Edition, and Symantec Network Access Control", which does not say outright that the same schema is used. It says only that "Each product includes the appropriate subset of the following documentation:" The Symantec Endpoint Protection Manager Database Schema Reference is on that list because that is documentation that we provide for releases.
If an updated schema guide is released, it would appear on this Documentation page. Check back.
