I'm just guessing here, but the Surface 4 Point component is rather "unstable" in the sense that corners will get crossed up some times. I believe this problem is in the Rhino SDK itself as I've run into this with Rhinoscript as well. anyway, if that's the case, then the extrusion won't cap bc it would make a non-manifold object.
It seams like what you're doing could be done a different way though, so do you have to do it exactly that way? Could you generate a plane and make the box from that? maybe do a morphed box if you need to...
