In this article there are two kinds of technologies being discussed - BEC and Anti-spoofing. While they are somewhat connected they are also distinct in their own right.
BEC compares the names defined in High Profile Users to inbound message display names to determine which emails will be subjected to extra BEC analysis. It is an extra layer of SPAM analysis that contains additional engines and features such as Writing Style Analysis and is specifically designed to protect a specific user base of High Profile Users. The High Profile Users list gets an extra level of protection and due to the overheads involved it is limited to 200 users.
In relation to general prevention of spoofing that is not necessarily a BEC function (although as developers advised, BEC analysis does part of its solution take account of SPF settings), anti-spoofing for the general user is more designed around implementing technologies such as SPF, DKIM and DMARC.
