There's nothing "odd" about it in the slightest. Chinese airlines want to be competitive, wield a considerable amount of 关系, and realize that trapping passengers in airports for 15 hour stretches is not cool.
72 hour TWOV entails a slightly different dynamic because in addition to the airlines, cities themselves crave additional spending from transit passengers.
