Just so.

If the restriction is added to an unmodified copy, then it is pointless,
for one can always go back to the copyright holder for another copy costing $0.
(Unless the copyright holder is dead, out of business, or bored -- the main
objection to the BSD copyright by GPL types.)

If the restriction is added to a modified copy, then all is hunky-dory.
The modified copy is not, of course, Open Source, but why should it be?
The OSD does not require that the copyright owner require that all derived works
are themselves Open Source.
