Basically, yes. Things should be connected (ie share a node) if they are physically connected in the real world. So a road which crosses a railway at grade should share a node (with the node marked as a level crossing) but a road which crosses a railway on a bridge or vice versa should not share a node. Boundaries, being virtual things rather than real physical entities are normally connected to physical things which cross them.
