Here is such an example. Suppose these are the sincere preferences:

49 A
51 B>C

Suppose that on the following cast ballots, A wins:

49 A
51 B

This shows an MD failure. It doesn't show an SFC failure, since those
voters preferring B to A are not voting sincerely (they aren't voting
the C preference).

Then suppose that on the following cast ballots, B wins:

49 A
51 B>C

This shows that in the previous scenario, there was no SDSC failure,
since the B voters could have voted in a different way in order to
make A lose.
