I have commits

A->B->C

and I am rebasing to

A->C->B

Git shows me conflicts TWICE. Why? Why are there any conflicts at all? Any commit is unambiguous. For example, if C is applied to A, why isn’t it possible to just apply whatever in C to A?

I understand the conflicts in merge, when two sources is combining into one result, but why in rebase?

What is conflicting to what?
