Because the each of the balls are spinning, conservation of angular momentum makes them not rotate sideways, therefore the top ball cannot roll off.
The friction between the two balls is quite significant, and the top ball is soft enough that its point of contact with the lower ball was squished into a depression, therefore it cannot slide off.
The two combined means the ball will stay on top.

According to this that means if you can get enough momentum going you'll always stay on top !
