Yup I heard that too. I think the speaker finally got it right. This reconstructed pronunciation which makes a c always a hard /k/ sound cannot be correct. Why would all the Romance languages have these differentiations for c and g when they are followed by e and i, rather than a, o, and u?
Without being sure, I think that this differentiation is considered by (some?) scholars a mediaeval evolution.
Anyway, the tips for the first lesson say that "This course uses Classical Pronunciation" and "C always sounds like a K", so this is a mistake by this course's rules.
It is a way of asking a question when you are expecting "no" as an answer. So in a way it could correspond to the English tag question, "The state isn't American, is it?"
