Green Building Q&A: Heat Bridge or 3-Dimensional Pressure Boundary

I stumbled on this interesting image a while back. I noticed that the caption refers to "heat bridges from structure and roof fasteners".... The fastener locations are obvious.... But the linear pattern does not look like a structural pattern(series of wood or steel rafters or joists). It looks more like a pattern of rigid insulation and the voids between the insulation.
