From what he has posted, Andrew2487 did not allow his "Bi-annual revalidation flight to expire" as it was never 'valid' for Revalidation purposes as it took place the 'wrong side of a deadline'.
I see what you're getting at. I read it that he'd left it too late to do the training flight. But indeed what he actually says is that the flight did take place, but too far in the past.
