At the end of SAO cordial codes Yui mentions that the The higher-ranked AI(white Yuna) has vanished yet Eiji denied this and said

"It wasn't like White Yuna…… Yuuna had disappeared. Inside Black Yuna, as memories…… as recollections, she continued to exist. She was still alive.

Firmly embracing Black Yuna, Eiji let out an unbearable sob. Indefinitely, indefinitely he continued weeping in a voice like that of a child."

From what I understand what remained of White Yuna went inside of Black Yuna in the form of memories instead of being completely erased

am I right in this what are your guys thoughts?
