The most probable reason for doing such a thing is better performance I suppose, as in the electrical CDMA (not always, though). And I made an 8in8 matrix for an 8 user system just as an example. But obviously the number of rows or columns cannot be less than the number of users.

All vectors created from matrix rows are orthogonal to each other, hence all vectors from columns. So you can pick any rows or columns.
