Wrong. Crimson Moon Arcueid is stated to be an aspect of Arcueid. There is no original CM anymore. All that's left is his "action ideology" (行動理念). It's explicitly stated in Archetype Earth's profiles both in MBAA and MBAACC, with no ambiguity whatsoever, that this "her" isn't a different personality, but one and the same as the usual her.
