Yes, it happens to work because the bootloader can treat each disk as a standalone device, but the bootloader has no idea if a given disk is failed, rebuilding, or in-sync. To reliably boot from raid you need an option-rom that understands the on disk metadata format and exposes the array as a single device to the bootloader.
