If a batsman hit score in few matches with having high coefficient of variation than other batsman,how is he relatively less consistent in batting?

In management paper,unit -8, at end of the topic of DISPERSION, conclusion of the example is like this Since average score of X is more than that of Y, we conclude that X is a better batsman. But batting of X shows greater Coefficient of Variation than Y. Hence, Y is relatively more consistent in batting than X.
