It points east, because the the long trough of the plane's impact points east.
Furthermore, if you are going to encompass the wreakage, than you are going to have to create an arc. Looking at overhead shots, again of the debris field, only an arc/crescent does it justice.
the design does not point East - its axis (perpendicular to the line of the gap) is oriented at 44.8044degrees north of East, or almost due North-East.
