I didn't understand this reverse curl thing. I thought that if you open the back of the camera by mistake, it's better if the back of the film faces light.
It is better not to open the back until rewound.

It's not that the film actually takes on a reverse curve permanently, but the inside out winding can open up the curve and that can make loading the reels easier.
