My guess would be that, if you need the carry, then it's going to feel like an over the top move to you. Maybe quite a pronounced OTT. But the point is to get you close to on-plane through the ball, maybe just a little out-to-in if you like a stock fade.
If you're watching the pros, then even the faders are going to look pretty close to on-plane. Most of them aren't going to look as if they're doing anything as extreme as the carry feels to you the first time you try it.
I think "feel is not real" gets over-used, but I think it applies here
