Yes, it works, if you can jump 2^64 iterations quickly. This is how xoroshiro achieves multiple streams. The PCG32 or the xoroshiro method guarantees independent streams. Using high bits in seeds doesn't have the guaranteed behavior. When you have many streams, stream collisions may become an issue.
