I think this is just a marketing stunt by the chief, they are feared of loosing the contract. EF beating Su-30 is a different matter which is debatable, but I do want to quote this thing and its also from that summary of Indra 2007:
While it does not imply to say that the 1 vs 1 air combat sorties were meant for backslapping each other, it may be understood that in today’s aerial combat scenarios of ‘beyond visual range’ (BVR) capabilities of air platforms, it is highly unlikely that any of the modern-day fighters will ever get into a situation that warrants extreme close air combat, as in the situation simulated in the 1 vs 1 sorties. With a ‘kill’ criterion of front-gun ranges being mostly under 1000 meters and a visual tracking envelope behind the target for only up to a 60-degree cone mostly for most fighter aircraft of the world, the unlikely scenario gets more exemplified.
