Grrr... an unfortunate typo for me. But, I'll fix it and expand:

You can install CentOS 7.8, and keep a host on CentOS 7.8, receiving
security patches that are on both RHEL 7.8 and CentOS 7.8, until the
end of the RHEL 7.8 and CentOS 7.8 life cycle. This is because RHEL
7.8 is a branch, and CentOS is regularly importing changes from this
branch, which means that CentOS 7.8 is also a branch.

Once RHEL 7.9 is out, RHEL 7.8 is "end of life", and similarly, CentOS
7.8 is also "end of life". Once RHEL 7.9 is out, the "c7" branches are
updated to reflect RHEL 7.9, and follow the RHEL 7.9 branch, as CentOS
7.9. If there was a RHEL 7.10, then it would be on a private 7.10
branch in RHEL, and run in parallel to the 7.9 that is being imported
into CentOS 7.9.

Everything you are saying about RHEL being some branch that lives
longer than CentOS applies to RHEL EUS, not RHEL:
