I agree, leave it in gear and turn the wheels towards the kerb: and I do doubt that they do teach it in driving lessons any more!
I am a biker and am always amazed when I see people parking bikes on the side stand facing the kerb i.e. pointing down the camber. All it takes is one little nudge from something to push it of the side stand, mash up your mirror, tank, fairing etc etc. I always reverse the bike so the back wheel is against the kerb and the front facing up the camber, so that
a) the bike rolls itself down the camber so you dont have to use any effort
b)gravity is pulling the bike down the camber and thus holding the side stand on
c) any slight nudge will not knock the bike off its stand
d) when you go to move off, you drive off normally i.e. use the engine to move the bike forward rather than having to reverse it up the camber by leg power.
And yes it appears that the test you did is what the pro's use to test the clutch, as seen on Watchdog.
