It can’t be the same person. This video was recorded at the same time the other guy was at NG’s house.I think he's alone. If you watch closely when he approaches the gate, I can see the gun holster swing out from his waist. He also has his jacket unzipped and places his hand at his waist a couple of time, probably because the gun keeps swinging out. I think it's the same dude. It's at the 10-11 second part. Enlarge your video:
Even beyond that the jacket is different, neither backpack is the ozark trail backpack, and his build is different.
