Imagine that you and I want to talk, and we don't trust the site to not look at the media we are sending each other. This is a mechanism whereby our two browsers are able to ensure that the media is protected from observation or modification by the site. In essence, the content of the media is marked as untouchable by the site in the same way that cross domain images can't be read or cross domain frames can't be touched in any meaningful way, except with express consent (through postMessage). If you are interested in learning more about this, I'm happy to explain offline. I'm sure that there are plenty of others who understand sufficiently too.
