On Rhino 7 it doesn’t work this way. On shaded mode you can select only visible edges/vertices while adding a crease, and this seems much more logical. If I want to select hidden edges, I would go with ghosted/wireframe mode…

It’s not a “bug” , but … well… it’s there. Surely not to put on priority though…
