I don't have an example off the top of my head, but what happens is that
raising the winner alters the elimination order in such a way that the
raised candidate can no longer defeat who remains.

For example, suppose in the first election C is eliminated and then A
defeats B. In the second election it's possible that raising A hurts B
more than it hurts C, so that B is the candidate who is eliminated. If
C defeats A pairwise then this causes A to lose to C.
