Well if he owned the car prior to it heading for Japan, that's entirely possible I guess.
This is the first time the car has been associated with "Michael" Andretti. As I recall, up to this point it's always been Mario that was supposed to have owned it based on the claims I have seen. That didn't make much sense given what Mario had to say about the F1 in the Road&Track article.
Nice find anyway...
