He would then be given "taking your own terrain clearance descent approved".
Also the 1000 feet above would not use the surface as datum but the highest obstacle.
So not totally wrong but a pretty clear way of explaining I thought.

I was looking at it from a Farnborough point of view after 7 years of retirement. In class G airspace, the pilots 'normally' asked for traffic service (or RIS as it was) to descend through cloud and hence I would not 'clear' them to a specified altitude but simply pass information as required. Bearing in mind Farnborough LARS sectors have/had a blanket of 1,500ft below which radar service is not provided except within the area covered by the Farnborough SMAC chart you would terminate radar service on passing 1500 and advise the pilot that further descent is at his/her discretion.
