TSForecaster splits, is data shuffled?

[ztsv-av]

Hello. When I create TSForecaster for time-series data and pass splits (array containing 2 arrays: first array with train indexes and second array with validation indexes), does TSForecaster shuffle data? In the docs it says: "splits: lists of indices used to split data between train and validation. Default=None. If no splits are passed, data will be split 100:0 between train and test without shuffling." So am kind of confused whether it shuffles time-series data when I pass splits (it shouldn't).
