You don't actually boot from a raid1, you boot from one of the
mirrored partitions that happens to look enough like a normal non-raid
partition to work.   And it is up to the bios on the machine to try
the 2nd copy if the 1st drive fails, and grub has to be installed on
the 2nd drive and configured to identify the drive the same way bios
will after the failure (which I don't think is always the same and may
even depend on the type of failure).
