Isn't it more obvious that the indices are the addresses of the locations if the boxes are arranged vertically? Besides the boxes should contain their values not their address, an address is attached to a box, and to one box only. Better off indeed thinking of pointer existing in completely different boxes and their values as pointing at the zero-width sides of other boxes :)
