It doesn't do the last command. That's the beauty of the initial ramdisk. it'll
automatically change the root device to the target specified as the root
parameter on the LILO argument line.

Neither. Happens automatically. Take a read of Documentation/initrd.txt in
any /usr/src/linux kernel source for details.

The kernel switches root from the initial ramdisk to the target root. I've used
this for mounting loopback filesystems as root too. Quite useful.
