It's actually a calculus/geometry answer - not an "ol geezer" answer.
The violation is for the ball passing over the "top" of the backboard. That is, if it passes by the "side" edges, there is no violation.
When you have a curve, there is only one point (infintesimally small) that is the true "top." Therefore, the ball would always be passing partially "over" the side - so a fan backboard doesn't carry a violation for going over.
