The use case is adjusting shapes by moving their vertexes, even if they are adjacent or overlapping another shape. Currently always the "later drawn" shape wins, making it impossible to adjust an earlier shape without re-creating it. Adjusting existing shapes is common for review scenarios. I have experimented with preferring the highlighted shape, but I found it finicky and less clear as to how the vertex preference works. JOSM (and OpenStreetMap editor) also uses the "prefer selected" approach and it works well there.
