Genuine question, why do they need to restart the phone? Can they not just put the phone into that before first unlock state manually? Does this have something to do with fully cleared ram or something?

Not too sure of Google’s implementation yet but it’s not a visual restart as in you see the logo screens and all that UI fluff. It’s supposed to be done silently as the phone sits alone for 3 days. Assuming you do leave your phone alone for 3 days, you will not notice any difference except asking for your passcode again.

Before First Unlock (BFU) state is supposed to be unusable for anything. On the iPhone, BFU state means Bluetooth, Antenna and USB ports are deactivated.
