Unfortunately, that is not true.  All you know is that the sequence is
extremely long, and that you can start wherever you want by choosing an
initial state.  But you don't know where in the sequence a given state
will bring you.

As far as I know (beware: I am not an expert) only multiplicative linear
congruential random number generators allow you to compute seeds
producing multiple sequences of given length which are guaranteed not to
overlap.
