Agree with both points. The guide is also missing steps (or mention of) moving the camera/sensor/etc to the new digitizer. I didn't think about it until I wondered why the old screen had 3 cables and the new one only had 2.
Unsoldering the motherboard is not necessary to replace the display. Once cables are disconnected from the mother board, the motherboard and the battery should remove as one complete piece.
