No actually they all did. Coen specifically was shown teaching her fencing . lambert teached her balance, geralt was the one showing her how to dodge and use the weight of an opponent to propel herself, and Vesemir was shown teaching her about monsters in a book . but likely all of them taught her.
but yeah i think the point of the video is showing ciri doing a move that geralt did in W2
