As an SFX demo reel, Panico is more impressive than the District 9 short. However the District 9 short is far better as a piece of directing and storytelling. I'd certainly hire the Uruguayan guy to do special effects on someone else's movie, but I'm not sure on the basis of this whether he has the skills to actually write and direct an interesting full-length movie.
Any amount of money would be would be worth it to them to keep him from making another.
They did credit the original composer so no harm, no foul - he'll probably get offered the job if a film goes on to be made, or else get a credit as 'music consultant' and a gratuity check without actually having to do anything.
