This is not surprising, since in both cases the velocity autocorrelation function, from which the mean-squared displacement may be calculated, is an exponential. It is unlikely that the detailed shape of a spreading pulse is the same at very short times, however, since the Langevin case assumes a Maxwell distribution of particle speeds.
