That's not quite standard terminology, as I understand it. In the "Supplementary Vote," voters may rank only two candidates. That's the system used to elect the Mayor of London isn't currently in use in the U.S. The top-two batch-elimination version of IRV, where voters rank more than two, is called the "Contingent Vote." It's the Contingent Vote, limited to three rankings, that has been implemented under the name instance runoff in North Carolina.
