It's open to interpretation, obviously, so your take on it is just as valid as mine. :P But, personally, I think it makes her death way more powerful if she thought she was never coming back. I took her saying "These are my memories, take care of everything for me, A2" as her hoping after seeing what she'd gone through, A2 would do the right thing and take care of 9S / tell him how much 2B loved him.

Also on that note, though, if they can store their data in their weapons, why the heck did they even need to worry about the storage on the bunker? Or was that more for being able to 3D print new bodies for their minds to inhabit? That's kind of weird, now that I think about it...
