=========
cwatters Had a look at the FDR link posted above but I'm no expert... It looks like something happened during the first encounter that caused the aircraft to exit the enclouner rolling right wing down. After 10 or 12 seconds it's 25 degrees down and during this time the heading changes 15 degrees. .............

I had to print these FDR traces out before I could read them correctly.
The label of the roll signal says, "Roll Attitude (+sense=right wing down)". The scale at the RHS shows + values plotted DOWNWARDS. Weird but true. So the a/c had its left wing down, not its right.
Note that the heading changes from 220 to near 205 during this period. The heading scale on the RHS is also plotted with inceasing values downward.
The a/c was responding to an ATC request to "587 heavy, turn left ...".
