Its just an innocent slight of the pen when marking up the map with city names. Probably happens at CNN all the time. Just like when a slight on Google's hand innocently forgets to put the lines in for Israeli borders, and calls the entire area Palestine. I can't say I know their motive for putzing around with French city locations, but I'm sure they have one...
Actually, I think it's a problem using overlays.
But the guy on the forum made very funny remarks.
