I interpret the application of the translation slightly differently for the North America situation.

The law says: "Any remaining seats shall be assigned to those lists for which the division calculations have produced the highest remainders."  I think that the significant thing is the use of the plural 'lists' and 'remainders', which implies to me that one seat each will be given to the two highest, ie L'Unita and Forza.

That also has somewhat more logic & fairness attached to it!
