The fact you are over coming gravity makes no difference! On the flat you are overcoming aerodynamic drag.............. it really makes no difference what force you are over coming, so long as you are putting out the same power.
The point re. pedalling style, you would have to clarify, the "style" is the same, the pedals are going around, you may adjust your position on the bike a bit though! I don't deny this.
I am struggling with this bolded part! Yes it can be done on the flat, not sure how you conclude it cant.
Spoze it can be don't on the flat. Buy a bike with extended forks.
What you fail to realise is the 'nose up' attitude of a bike on a hill incline. The rider's whole body will be in a different position with relation to the headset and handlebars. Try assuming the same position on the flat and you will end up supporting your upper body weight with your arms and not using it to stamp on the pedal.
The only place to hill train is up a hill.
