Also, Tensura operates on the multiverse concept of theoretical physics. Nothing someone does in one timeline changes the effects of another, because it just branches a new timeline. There are worlds where Yuuki won, where he lost, where Rimuru was never born, where Satoru never died. It has no real effect on the events of those times, if only that Rimuru can observe the effects of changes by watching them unfold in another timeline. He wouldn't experience them, but he could see how they would have happened. For example, by saving himself, he gets to see the life he would have lived had he not died, even if he himself doesn't get to live it.

That's one of the cool things about Rimuru's ability to warp through time, is that he can see the effects of decisions taken or not taken, he can see the "what ifs", and learn from mistakes her never committed.
