Is the picture showing the debris field an indication of the plane´s heading?
No, of course not. It shows the direction of the debris, as it sank.
An a/c that is rotating, laterally, out of control, cannot have a heading.
The "system" as it falls, can have a direction, though "random".
The direction of the nose as the a/c impacted is random, undirected, and most definitely not commanded. For the umpteenth time, "En Ligne de Vol" is a fantasy.
