No, she must be american. The american red cross organisation has copyrighted the sign of a red cross so it's not possible to use it for free. Many who didn't want to pay just switched the colors. Maybe they didn't know, that this will be the swiss flag. I don't know if the were aware that they are going back to the roots someway. The founder of the red cross, his name was Henri Dunant, wanted a cross as a christian symbol for charity and because he was swiss, he take it's flag and swaped colors!
