[Plugin: Jetpack by WordPress.com] Jetpack shortcode video embed support for html5

Hi
I guess jetpack plugin is so useful for several purposes. however i don’t know if the shortcode option to embed video from youtube use the feature from youtube to embed videos through iframe element and to send video in both formats, flash or html5, according to the preferences or environment, as youtube suggested to do:

the code generated should be:

<iframe class="youtube-player" type="text/html" width="640" height="385" src="http://www.youtube.com/embed/VIDEO_ID" frameborder="0">
</iframe>


I guess Jetpack doesn’t support it, could you tell me if I’m wrong? In this case, how it’ll support it?

Thanks in advance
