The footage is blurry, but notice the body language of the attacker. He is deliberately trying to appear relaxed and inconspicuous, but he is immediately recognizable as a potential threat if you are alert.
First, he is standing with his back to the wall, tensely fixed to that spot.
Second, he is constantly looking back and forth, with his gaze always returning to the back of the sister.
Third, his hands are behind his back, which can indicate concealment of intention; also, when backed against a wall, having the hands behind the back can suggests that someone is preparing to move suddenly, using the hands to propel themselves off the wall.
Fourth, his posture is slightly bent forward, and not in a relaxed manner, but rather in a manner that indicates readiness
And notice that the sister is completely unaware, she never looks around her, never looks behind her, and is fully relaxed with no consciousness of those around her.
