Upgrading versions of Sequoia with OCLP installed

I'm currently using OCLP 2.4.1 to run Sequoia 15.7.3 on two MacBook Air's and one MacBook Pro, none of which support Sequoia without OCLP. All three run flawlessly, and I've had no issues that I can detect. I've been able to do "in-place upgrades" (directly from within Settings) from older releases to newer releases of Sequoia without incident (but of course I have to re-install root patches after the upgrade completes).

In a video I just saw, Anson Alexander upgraded from an older version of Sequoia to a newer version of Sequoia by using OCLP to download and create a MacOS installer, then installed the Installer using OCLP to disk, and then rebooted to apply the upgrade, then re-installed root patches when that was done.

Is there something I missing about just doing an in-place upgrade from within Settings? Is there a reason why his method is superior? Or are we effectively doing the same thing?

For what it's worth, I *DO* make a full OCLP Installer with the new version of Sequoia on a USB drive as a back-up (basically like the first time I installed OCLP), but I've not needed it.

Thanks for any insights anyone might have.
