-Sort Down always [matches](match.md) Sort Up [reversed](reverse.md), `⌽∘∧`. The reason for this is that BQN's array ordering is a [total order](https://en.wikipedia.org/wiki/Total_order), meaning that if one array doesn't come earlier or later that another array in the ordering then the two arrays match. Since any two non-matching argument cells are strictly ordered, they will have one ordering in `∧` and the opposite ordering in `∨`. With the reverse, any pair of non-matching cells are ordered the same way in `⌽∘∧` and `∨`. Since these two results have the same major cells in the same order, they match. However, note that the results will not always behave identically because Match doesn't take fill elements into account (if you're curious, take a look at `⊑¨∨⟨↕0,""⟩` versus `⊑¨⌽∘∧⟨↕0,""⟩`).
