It wasn't a completely vertical dunk. The ball had significant downward momentum, but also significant horizontal momentum as well. If you look at it in slow motion, it looks like it also grazed the rim, giving it even more misdirected horizontal momentum. Without getting into the actual physics, think wave motion. Similar to when you have 2 people hold each end of the rope (net) and one whips the rope down. The 'whipper' gets a reaction when the wave comes back from the opposite stationary point (rim). I think the 'grazing' may have also had an impact in starting or at least contributing to the the 'wave' action of the net.
