Article with multiple autoplay videos

[cramforce]

I think it would be super awesome to have a high quality example of an article-type page with multiple autoplay videos.

CC @aghassemi who is building this on the AMP side. ampproject/amphtml#4154
I think Ali also submitted an example to the main repo showing this. We currently support amp-video and amp-youtube.

Agreed.
no autoplay for <amp-youtube> yet though (have a prototype, still needs work to be merged).

Adding an autoplaying video for the Recipe sample would be nice too.

The page @cramforce is referring to is here: https://github.com/aghassemi/amphtml/blob/master/test/manual/amp-videoplayers-autoplay.html

Which use cases should we demo with this sample?
