I don't think that the Indian court has legitimacy to block the article to be displayed worldwide. It has no jurisdicition for the citizens of all other countries and also no jurisdiction against content that is not hosted in India.
But I guess that it was maybe more convenient for the wikimedia foundation to do it like that instead of doing geofencing that they might not have?
