Ok so you get a TRUE report on your condition and awarded correctly for a duration of say 3 years, But, after 2 years you have to go through the process again and they find you 'fit' as a fiddle ( in their eyes!) and you have your original award quashed! Given that the original award is for 3 years because the given evidence is read as true with medical evidence along with their reports, Is their new decision an admission that they made a mistake at the first interview given that your ailment is life long and very unlikely to change!
