Magnetic reconnection

Does RST or RS2 have an explanation for what astronomers call "magnetic reconnection"?
I was triggered by this article and the great animation that goes with it:
www.nasa.gov/mission_pages/themis/auror ... power.html
To me "crossing magnetic field lines" that "reconnect" look unphysical, at least to my Maxwell trained mind.
The wikipedia article at least partially agrees with me: "A current sheet (as shown) may be present but is not required for reconnection to occur. This process is not well understood: once started, it proceeds many orders of magnitude faster than predicted by calculation from first principles."
It is here: en.wikipedia.org/wiki/Magnetic_reconnection
"As a limiting case, refrigerator magnets moved near one another in Earth's atmosphere cause nearly continuous magnetic reconnection, although no electrical current flows through the air .
Could it be explained by a "magnetic charge" redistribution?
