Uh-oh, Bus doesn’t defeat BF. But Bus can’t be defeated.

…& so wins unless someone else is un-majority-beaten due to lots of
truncation.

I guess Bus could eliminate CW before BF meets CW. …& CW was BF’s only
defeater.

But BF *might* be eliminated, & Bus can’t be eliminated (because hir only
top-cycle defeat isn’t helped by the defensively-truncating CW-voters.  …&
Bus, as a top-cycle member, has no defeats from outside the top-cycle).

So, probabilistic-deterrence.
