Not some fool, a rocket scientist. It's not mis-information, it's a fact.

To burn the fuel you have to mix it with oxygen. It is not extrodinary at all that measurable amounts of fuel would remain unburned when you consider the speed at which the ship fell apart, and the altitude. Very thin atmosphere at that point.

Pieces were getting blown off and flying off due to Ge forces. Once they got away from the oxygen in the fireball they would burn out from lack of oxygen. Explosions can put out fires as well as ignite them. That's why they use dynamite to stop oil well fires.

EDIT: But beyond that, they weren't saying the hydrazine fuel was the only dangerous substance in the debris. Many chemicals that are toxic are not flamable.
