No, this is independent: first of all the Spain-Morocco interconnection predates the Desertec project by half a decade, and survived after its demise, but it has never been designed to be able to carry that much electricity (it's barely capable of carrying 1.4GW): it cannot be used for significant export and is there for grid stability alone. Had you read the Wikipedia page you posted, you'd have realized that they planned to use dedicated HVDC lines under the Mediterranean to carry the power, and not the Spain-Moroco interconnection.
