They had me until "the magnetic field lines act like a spring...""These solar tornadoes are almost a thousand times faster than a terrestrial tornado and are very big," said Spiros Patsourakos, a researcher at George Mason University.

"The main element [of the new observations] is that the erupting structures possess twist," said Patsourakos, who described his findings last week at an American Geophysical Union meeting in Fort Lauderdale, Florida.

"The magnetic field lines act like a spring, which expands and jumps outward," said Pariat, who has used computer simulations to model the forces producing the jets.
The forces originate in the solar interior, he added, where the sun's rotation twists the magnetic field.
Umm, how about this for a better solution:

The helical twist may simply be derivative from electrical / magnetic forces acting upon proximal currents. Long range attraction + short-range repulsion tends toward a helical arrangement...
