I suspect there's some weasel-wording going on here.

It may be real video-footage, taken of real devices in a real room, which really moved and really emitted sounds... And still be staged as all heck.

Skepticism is especially warranted when such a "miscommunication" means the company could gain ridiculous amounts of viral marketing.
