While I love pedantry, and find interest in the confusion and irritation using "American" to mean "U.S. Citizen" can cause; in this case, using American is fine for either definition ("U.S. Citizen" or "Person who lives in the American continent(s)"). Either way, the comment is correct and has similar meaning. :D
