Wouldn't the burning of the paper technically make it powered?

  No, the burning of the paper removed a great of mass from the paper turning to to a brittle paper ash. After the fire was out is when the timer started, since the paper ash was so much lighter but the same volume its buoyancy in air was drastically increased causing it to "float." The up draft from the flame wasn't utilized to power the flight, the fire was only used transform the original rolling paper into a "plane" by mass reduction through combustion.
