Yes I'm.
Extract from europe.osm.pbf (geofabrik) with a selfcreated polygon file. I tried also an extract with a bounding box (values from your HowTo).
Perhaps parts of the border are also used by other tags, e.g. "natural=river + boundary=administrative". If you have a rule in your style which matches the "natural=river" you won't get the border.
It's definitely a shortcoming in the multipolygon processing. WanMil
