I always understood export for a link state to apply to external only. Internal routes have to be flooded for correct protocol operation, minus certain rules for L1/L2 or for ospf stubby areas, but filtering these internals is not done with policy.
In this context the doc link makes sense. While a bit surprised it worked, you seems to have overrode the default deny all externals export with an explicit deny all, which also caught internal routes.
