Yes - it is a strange but quite common illusion!
Another similar is a wire-frame 3D drawing of a cube, angled at 30º (isometric view) so the near top corner conceals the far lower corner; and the near vertical edge covers its opposite edge. It can similarly invert itself in your mind, or become a hexagon with its apices joined to its centre.
I am trying to teach myself CAD (computer-aided draughting), and sometimes outlines and geometrical locations in 3D views can be the very devil to read properly by similar effects.
A café I know has a view from certain tables of a portico on a shop diagonally opposite, which in certain lighting conditions after dark gives that feature an odd appearance reminding me of an M.C. Esher drawing.
