As I understand it, all points below the threshold value of the 
isosurface are considered as inside the surface and all above as 
outside. All points on the surface of the containing box or sphere of an 
isosurface considered as part of the interior of the isosurface are 
closed. The open keyword removes this coating.

This explains the behavior here. But I my be wrong again.

Best regards
