Amongst the silly things written on the Internet page :

"Qu’est-ce que des Miles-Statut ? (...) Les Miles-Statut ne s’obtiennent qu’avec la carte AIR FRANCE KLM AMERICAN EXPRESS GOLD. "
"What is a Miles Statut? (...) The Miles Statut do come only with the AIR FRANCE KLM AMERICAN EXPRESS GOLD card"

Don't expect to get Miles Statut when flying Skyteam...
