This way they achieve an overall constant temporal privacy loss throughout the time series. According to the technique's intuition, stronger correlations result in higher privacy loss. However, the loss is smaller when the dimension of the transition matrix, which is extracted according to the modeling of the correlations (here it is Markov chain), is larger due to the fact that larger transition matrices tend to be uniform, resulting in weaker data dependence.
