The machine may fail before the userspace is established enough to be able to write back to somewhere the boot loader will then read, and such a boot *must* be counted as bad. And the only way to do this is to actually do boot counting in the boot loader. It is the OS that marks the boot as "good", but it's the boot loader which decrements the boot counter before each boot, i.e. it actually implements the counting in boot counting. Both systemd-boot and grub2 do this.
