I am no expert on video analysis, but to my unprofessional eye, which looked at this video more than a dozen times in regular and in slow motion, it seems to indicate the exact opposite of what the article claims it proves. Sure, the grenade passes near her. However, it clearly passes above her head and continues in the same direction. Moreover, she clearly begins to fall down before it reaches her. Which leads me to one of two possible conclusions: a) She was injured from the sound and/or power of the grenade passing too close to her, or b) The grenade coincidentally passed near her a second or two after she was hit by a stone that came from another direction. Look at the video objectively and see if I am not correct.
