It's alloy, not pure magnesium, so it doesn't ignite at the same temperature. The article states that ignition temp is 650 Celsius which is pretty damn hot (compared to 475 or so for mag ribbon). I bet you'd have a hard time getting it to ignite even if you deliberately tried, because the heat is going to rapidly dissipate across the unit.
