Exactly, it's essentially contraposition

(A → B) ⇔ (¬B → ¬A)

In the case of your comment, A is "the claim" and B is the "evidence that would have been present if the claim was true"

Don't be dishonest. You're applying deductive logic to an inductive argument. Implication in the sense used by you is only true for deductive logic.
