These are special shapes where all the vertices keep their lat-lon position positions as the projection changes and the edges between them are sampled linearly in lat-lon space. It means that in cylindrical projection the edges are always straight lines, while in other projections they might be curves. The following table shows how a fitted geo-shape changes as the projection changes from cylindrical to polar north:

For these objects only the centre (for the text the top left corner) keeps its lat-lon position as the projection changes, while the extent is defined in terms of pixels.
