Yes, I understood that.... I took it as her saying that she personally had never been out of New York, but one of her alters had gone to Hawaii, therefore, in reality she "her mental self" with having no regulation of ever having been out side of New York was telling the truth in the World of DID.

Example:
I dont type well, but one of my alters can type a mile minute, but if you ask me if I personally can type - I would say No and that would not be a lie even if you were to see typing away... she has to be present for me to type.
