I do not think the clips are very strong.
The volksgrenadier sandbag clip vs. pathfinders: it is normal to be looking at your volks when they are building sandbags when it is early game and you are in the frontline. Hitting the stop button as soon as you see a Pathfinder is very normal. Tactical map users can also do this rather quickly as we saw in tournaments with Luvnest repositioning MGs with quick reaction time.
The sniper clip (6:15): moving away your sniper from unknown territory where you might be countersniped is normal. He had no support infantry covering his flank so it makes sense to move his sniper westward. He knew his opponent had a sniper and is reasonable to be cautious.
The brumbar clip (4:30) is the only suspicious video, and only the first shot on AT guns. The second shot on the other hand had an uncloaked AT gun nearby
