Does physics entity order influence the deterministic result?

For example :
I have tow physics world,I add them the same set of rigidbodies,but adding in different order,does the two world get the same result if I then step the world?

more question:
I have two physics world, one add some rigidbodies and later remove some of them,leave rigidbody set A,and another I direct aad the rigidbody set A into the world ,does the two world get the same result if I then step the world?

Yes order affects determinism. Generally speaking all deterministic data needs to live together in an isolated world.
It would be a bad idea to put any data that is non-deterministic into the same world.

(Both for the ability to validate determinism & generally because it might reorder entity iteration)
