It feels like this is just a play on words. Consider a camera connected to a monitor. The camera captures 24 frames a second and sends the images to the monitor via a cable. The monitor displays this "live" feed. Is it really live though? There are multiple buffers and busses that the images have traveled through, sometimes even staying in one place for many milliseconds, as some resource lock is being acquired. Despite all this, would you say that the monitor is displaying stored data? Technically yes, but for all practical purposes no.
