GRUB reads grub.cfg either from the device BIOS had booted from (sans

I asked him to explain how GRUB was installed on both devices but he never
replied ... besides IIRC original question of about EFI, not BIOS.
EFI would make a difference. I would very much expect EFI to tell the
bootloader which device it was started from.
Legacy BIOS is expected to do it as well.
After all EFI isn't BIOS, so if someone says BIOS I am going to assume
that is what they mean. :)
"BIOS" is often colloquially used for "firmware of my system".
