I am not a lawyer neither, but my view of this is that the map (rendering) being licensed whatever doesn't mean there cannot be other rights involved at the same time. Eg a photo of the coke logo could be licensed pd but that doesn't make the logo pd, a pd series of photos of a disassembled product don't give you the permission to re-engineer that product etc., so even if the rendering is released as pd the underlying data still remains ODbL and when you extract it it will be under ODbL license and not the license of the rendering itself.
