do you have a trampoline? because i have found that once you have learned a specific flip on the trampoline, with a little work, it is quite easy to translate it to the ground or off of a small height. and about form, the trampoline is a great place to learn form, so i'm not sure what you are getting at there.
I think he means when transferring from the trampoline to the ground, you are used to the form you use on the trampoline. You have more bounce, you don't have to tuck as much, you can easily jump forward and still get the rotation you need on a trampoline. Whereas, on the ground, you don't have that extra bounce, you'll have to tuck harder, and you can't jump forward, you have to jump up. (Assuming you're doing it off the ground) Otherwise, even then, doing it off of a small wall, you'll still want that memory/form to jump up and not out.
I think the best way to transfer something over like the front-flip from a trampoline to the ground is to get SO comfortable with the front-flip that you can do it from standing (not even one push down with the legs) on the trampoline, and even then it will be a lot different on the ground.
Edit- Oh, and blocking, can't forget blocking

You don't need blocking at all on a trampoline, so when you move to the ground, you'll have to learn a whole other technique.
What I did was just go to the Long Jump sand pit at my school, and plant my feet at the very end of the run, and flip into the sand pit. I would see how far away my feet were from my initial take-off, and over time of practicing it on the ground, I eventually got closer and closer, and the closer I got to my landing, the better the landing was.
