[She'll probably have to adjust her aim as he moves - he wasn't just standing idly by after his attack connected. By the time she's pulling the water from her waterskin, he is turned back around facing her, kneeling and hands in the rat position again, though his shadow is only now moving.
Due to the sun's position, his shadow has more distance to stretch than it would if she'd been continuing to fight him from the other direction, so there is time there. On the other hand, the stream of water makes a nice shadow on the ground for his to pass through and get to hers unless she releases it and moves back.]
