If you look at the two paths of the cue ball in the Sharivari video for separate (non-overlapping) contacts, the paths are quite far apart. The path in the stream video was very close to one of those paths. It is possible that there was overlapping contact, but that is still hitting one ball first, and I think for this shot, the first ball is obvious from the path of the cue ball.
I think that if high speed video had been available -- 10 or 20 frames during each ball-ball contact, so 10,000 FPS -- it would have been very clear which ball was struck first, even with overlap. No tournament has such equipment.
