Sure, although this article is talking about the overall two-party preferred preference flow in electorates, with Labor vs. Liberal/Nationals as those two parties. So purely in this metric our valid votes will flow to ALP or L/NP even if we preference them as our last options, and even if our local electorate doesn’t elect ALP or L/NP. If the two winning candidates in an electorate are Greens followed by One Nation, the two-party preferred preference flow chart will still only record whether you preferences ALP above L/NP.

And you’re still right, that absolutely can change, and we have some power to change it, but it takes more than us directing our own votes to make that change.
