ah okay what you are doing will work and it will also initially create the affect you are seeing. The reason is that until you merge the vertices at the top and bottom you are collapsing the top and bottom faces to zero surface area. This can create the strange black faces to occur.

To help demonstrate look at the attached image and you can see just before I snap the verts that there is a face on the top. That face does not go away when you snap the verts and creates an L shaped face with no area and it causes the display artifact you see.

There are many ways to do what you are doing. If you merge the verts after snapping them that odd black face will go away.

Another way would be to select the merge vertex tool and then you can snap the verts (without needing to use the v-snapping) and they will also merge.

Or you could extrude the sides of a cube.

There are lots of ways to do the same thing in maya.
