I think the starter method is like what we called "riding it up". It won't work on modern bikes with tilt sensors. It also didn't work on bikes with carbs that wouldn't pick up the fuel at extream angles. With the bike on it's side, you'd start the bike, put it in gear and release the clutch as you stood next to it and lifted until the tires got contact. With the steering to full lock in, the bike would try and stand itself up. And yes, sometimes the bike would end up laying on it's other side. All things considered, (starting, reaching shifter, etc.) it was safer and easier to lift the bike dead. I've done it on simple tip overs that never stalled the engine (British Twins and dirt bikes), but never on a full size HD. Kind of a cowboy move, but when (if) it worked, it was rather impressive.
