Actually the nice thing about an RCD, at least when it is working, is that it is current operated, not requiring a specific voltage on the CPC, so the state of damp of the victim is less important than safety systems that are relying on keeping a touch voltage to a specific level - a voltage that is safe to touch when dry may be far less safe to the wet hand.
However this seems to combine a non-tripping RCD and a loose live wire in the loft, the latter would be getting more of a mention if it was me.
In any case a tragic event, probably avoidable with the right sort of inspection and test, but you'd still have to test a lot of properties very carefully to save one life, I suspect many inspections would still miss things like this.
