What is the intended use of the `pauseAnimation` player config option?

I'm recording and playing back in liveMode a single page app that uses animation between routes. The animation is css based. With the default configuration, the replay appears broken when moving between routes because the animation is never run. If I set `pauseAnimation` to `false` it works as expected. I'm just wondering what the intended use is for the `pauseAnimation` config option.
