I don't see Johan going along with a plan that pins it all on him in the end , not for any money - he would have preferred an exit plan that got everybody off squeaky clean, his demeanour and Cheri's reactions in the last video do not suggest to me these where people comfortable with an unfolding plan.
Never mind the rolling video, get stills of their faces at key points you will see johan sheepish almost uncomfrotable almost knowing that by now Cheri has cottoned on and even the occasional smirk.
I am sure at one point he tried to show more of the room by trying to move the camera maybe to drive home the point or to convey his location to someone - (best friend, wife?) or perhaps he realized what was in view and wanted to hide it - but too late
