Those rules appear to intertwine flight conditions, pilot ratings, sight of the surface, altitude, distances in meters and feet, airspeed, and aircraft airworthiness category in a completely indecipherable maze.
See my earlier post with regards to pilot ratings and aircraft airworthiness.
As far as the definition of VFR in the different airspace classes is concerned, yes, there seems to be some sort of mandate for ANO writers to put at least a triple negative in any article written. Cases like this, the AIP is a much better source of information.
UK AIP, ENR 1.2 para 1.1 has a very handy table for VFR requirements in all classes of airspace, at all altitudes. Unfortunately it's impossible to cut&paste it here, but the link below should take you directly to it.
