The point is, to get the most height on the front, you do push into the ground first for pre-load. Ash is merely saying it's possible, not recommended, to do without. He's right - you can just lean back and pretty much pull into a manual and hop straight away. It would look slower than most bunny hops - laboured if you will. I think that's the point Ash is trying to make - it could be done. It's academic, and somewhat misleading to the thread.
So it's not so much wrong that you're springing off the forks, because the action is correct, but if you were putting any effort into it, you'd be getting more height on the front than that. You are currently relying on the spring to get you up a little. Nothing to be ashamed about, just something to consider next time you're trying. You need to work on shifting your weight back and forth.
