Outflow boundary condition

I know that in outflow boundary we assume a zero normal gradient condition and use upwind scheme for approximation. However, I saw this sentence in a book which I do not understand; "Convective fluxes are usually assumed to be independent of the coordinate normal to an outflow boundary." What does it exactly mean and why are we allowed to make that assumption?
Thanks. |

it means that the normal derivative to the outflow plane is zero
