Every other voting system anywhere on the planet treats a ballot
mentioning only X as preferring X to all other candidates.
Every other preferential voting system treats a ballot ranking X 1st,
and Y 2nd, as a preference for X or Y over all other candidates.
That is how voters expect these systems to work.
Our voting system treats a ballot mentioning only X as expressing no
preference whatsoever.
