We're talking about different procedures here.
From July 10, an IFR aircraft in Class E airspace, can request to operate VFR-on-top. This essentially changes the service provided by ATC from Separation to Directed Traffic.
The IFR aircraft can then changes levels according to Class G requirements but can only level out at VFR levels.
A VFR aircraft operating VFR on top has nothing to do with ATC, but is simply a term whereby a VFR aircraft is operating above cloud but can still meet position fixing requirements.
It really would have been a lot simpler if the A.R.G. had coined a new phrase for the IFR option.
Cheers.
