From the article
"the likelihood that the satellite upon descent to the Earth's surface could release much of its 1,000lb plus (454 kg) of its hydrazine fuel as a toxic gas..
....If the hydrazine tank did burst, the danger zone would be an area covering the size of two football pitches. He said that blowing the satellite up would disperse the hydrazine harmlessly in space, leaving only small-scale satellite debris to fall harmlessly to Earth."
