Hmm I guess it would make sense. With magic attacks, it will dissipate. With physical attacks, it will either go 'plunk', or pass through. Though it concerns me, even those projectiles shouldn't really do damage. So my guess is that Acnologia was simply showing off or something, as he can't just absorb the projectiles like what he did with the magical beam.
