I'm almost positive they're tracking every dragon you exalt even after you get the achievements. There's no reason not to; it's just incrementing a variable and they probably want to add more achievements in the future.

in fact, they must be tracking them somehow, seeing as every dragon you've ever exalted changes which deity they serve if you change flights
