Yes, but, in fairness they never said it was, and mentioned that it was fitted to later versions, which it was, as the E Wing fit MkXVI's used by the RAF in the last year of the war had the inner 20mm Hispano replaced by a fifty (and no outer .303's)
Also, live a/c fit Browning .303's are a tad thin on the ground, hence having to make do with the fifty for the demo.
