Its just marketing type. Its like saying Champagne is not Champagne unless it comes from the province of Champania.
Montecriso makes cuban cigars too. Ive had Montecristos grown from tobacco in Central America and tobacco in Cuba and you cant tell the difference.
Also if you are in the US I would not try to order Cuban cigars from Switzerland (from the link posted above) that is still violating the embargo.
