Wannabe, you're confusing 'Visual Flight Rules with 'Visual Meterological Conditions', and 'Instrument Flight Rules with 'Instrument Meterological Conditions', and the logging of Instrument Flight time (IF)

Flight under VFR requires VMC however flight under IFR can occur in IMC or in VMC. VFR presumes that the aircraft can be controlled by visual reference to external cues. IFR does not - however it doesn't prohibit it either, if meteorological conditions are suitable. That an aviation authority specifies that a particular set of rules must be used above a certain altitude is irrelevent. USA uses F185 for mandatory IFR, Oz uses F245, and the UK uses F200. Apparently where you are uses F195. To follow your logic, it's possible to control an aircraft perfectly satisfactorily using external references in Oz at F210, but suddenly become incapable the moment the aeroplane crosses into the US or your region's airspace at that same level. So you can easily be operating under IFR and be in VMC, and controlling the aircraft using external references, no matter what altitude you're at.

The rules that allow you to log IF are pretty similar in all the regions I've flown: You must be controlling the aircraft by sole reference to the instruments (or providing inputs to the autopilot). If you're using external references then IF is not loggable. Nowhere in the IF logging rules is it a requirement that you must operate under one set of rules (IFR or VFR) or another.
