That was a rhetorical question after I pointed out the inconsistency: The author claimed they keys were for verification and then also said they were used to decrypt.
That’s most likely bullshit, and if it isn’t they should explain the unusual setup in detail instead of glossing over it.
Maybe I am missing something but I think you answers your own question?
ROM is Level 0, it has the burned-in, permanent key. It hashes and verifies the Level 1 bootloader, on disk, signed with the ROM key.
Now that the ROM key is known, anyone can sign a PS5 bootloader; and you can pretty much do whatever you want from there.
It would seem that all existing PS5s just went up in value.
