Is this a flush mount or surface mount installation?
If its flush mount then I do not see a problem with your cable installation. The bundling argument is kinda weak for residential, as there are very few continuous loads in residential. If its a loose bundle it should be okay.
If its surface mount, then his problem maybe with no protection from physical damage.
Since he has a problem with your spare conduit, I would terminate it in a proper size pull box.
