[YouTube-API] Bug? The "playing" event fires twice for HTML5 iframe player

I used the example code here:

http://apiblog.youtube.com/2011/01/introducing-javascript-player-api-for.html

In the onStateChange callback I'm logging evt.data:

function onPlayerStateChange(evt) {
console.log(evt.data);
}

Test: load the page, then press the play button.

Results:

Desktop (chrome):
-1 (unstarted)
3 (buffering)
1 (playing)

iPad2 Safari:
3 (buffering)
1 (playing)
3 (buffering)
1 (playing)

Here's my example: http://www.calebolin.com/code/demo/iframe.html

Is this a bug?
