Formaulaire S1106

Je suis anglaise et a la retraite en je veux obtenir une carte vitale. Je viens de lire les pages en anglais qui me disent:

Your principal residence is in France, and you receive an invalidity pension (incapacity benefit) or retirement pension from your country.

Please, provide us with a copy of form E 121 (S1), in duplicate, for you, and for each member of your family.

You must also give us :

the printed Form application for the right to health insurance (S1106) (PDF) ;

MAIS, quand je lis le formulaire S1106 il dit

If you are a member of another country’s social security system, e.g. as a worker on a posting to France from another country or
as a pensioner, do not fill out this form.

Ma question: dans mon cas, est-ce qu'il faut remplir le formulaire S1106 ou pas???

Merci pour vos reponses.
