Answer 1

because the cursor is angled down and to the right. the tip of the cursor is the pixel you use to click, and that pixel is confined to the screen, but the actual shape of the cursor doesn’t need to be restricted in any way

I guess more accurately, the pixel you use to click needs to be able to hit the edges of your screen, so the cursor’s shape *needs* to be able to pass behind those edges
