AFAIK this is correct. I don't think anything actually uses initrd
anymore but the name has stuck around - to refer to either initrd or
initramfs. Even the plymouth initrd image is actually an initramfs (I
believe).
Some reading for the interested:

FWIW -- there are/can be some compression differences from the early microcode
stuff. I'll ping the anaconda folks at some point to see about switching the
name to initramfs instead of initrd.
