That's my understanding as well. The problem, though, is that the virus doesn't completely peter out because it survives in the bats. There is a possibility a mutation makes the virus less lethal, in which case it could cause much more problems when it jumps again from bat to human. Maybe next year, maybe in a hundred years, maybe never. Disclaimer: I'm absolutely no expert. The above is only my best guess.
