The replicated fire is an extension of Lawrence power/self, so it is independent from the source of the original fire, meaning each would have full control of his own fire.

When materials/phenomena are absorbed, they simply cease to exist while he gains all the coresponding knowledge and power, so it doesn't have any influence on him.

Judging from Lawrence's power origin, his main absorption/replication abilities would work on anything, while replicated abilities would be limited by their specific context.
