[Spoiler] Was Brandon Wan left behind?

[PiratesFr33k]

Does anybody remember if Brandon Wan had his brain scan on the ARK?
In Theta, Simon puts the copy of Brandon in that simulation in order to get the security cipher, as you'll all remember. But that was just an "additional copy" we got from the original scan, right?

Somewhere on the web (I think it was on Reddit or the Steam forums) I read that people were angry about Catherine only giving you the option of erasing the Brandon Wan data or simply shutting down the system. (Well... first of all, it wasn't Catherine giving you those two options. The computer interface itself only had those two buttons.) The people in that forum thread thought that there should have been a third option in which you could choose to take Brandon Wan's data with you and put it on the Ark.

But that's redundant, right? Brandon Wan's data is already on the Ark, isn't it?
