You may not reset the legacy stream using a seed

reset(s)

resets the generator for the random stream s to the initial internal state corresponding to its seed. This is similar to clearing s and recreating it using RandStream, except that reset does not set the stream's NormalTransform, Antithetic, and FullPrecision properties to their original values.
