Reason behind additional '-(void)play' call on @"playbackBufferEmpty" observation

[squatchus]

Hi.

Is there any particular reason to call 'play' method when AVPlayerItem @"playbackBufferEmpty" property observed? It leads to multiple call of 'play' when you try to play downloaded file or stream from web. It generates some issues with inheritance and it seems like everything works without it. Just curious why its there :)

Thanks.
