Clipping start is negative when the viewport preview is used with the orthographic view, while Freestyle assumes that imported mesh data are in the camera coordinate system with the view point located at origin. The present solution is to adjust the clipping start/end and introduce a Z-axis offset for mesh vertices so as to satisfy the assumption.
