That's because the layers you still saw at those zoom levels didn't
reference those missing columns. The weirdly coloured roads you saw, for
instance, were only drawn in their casing, and couldn't be filled with
the core colour because that style actually referenced a missing column.

It's always a good idea to keep osm.xml, default.style and osm2pgsql
synched to each other. If one of them falls too much behind the others
in features, you can get those strange effects or other undefined behaviour.
So you're welcome to add such a note to the respective documentation,
