I believe he's implying the use of the satellite as a repeater and the intervening space as a delay line

I do not think it's viable in any sense with launch costs but in a hypothetical scenario where you had something 20 light minutes away with a channel that had no better use you certainly could buffer 40 minutes of data on the channel

It is limited here not by the availability of space but the ability to collimate the signal and the availability of power density at the receiver to discern the signal from noise

Yes indeed, I imagine a situation where some natural resource is modulated such that, 20 minutes later here on Earth, 1000's of Petabytes of data is received such that, if re-transmitted, it will be reliably received across the distance of space. Lets say 20minutes, 1 year, 10 year and ... 1000 year intervals .. might be the line item deals on offer.

Truly a sci-fi concept, inasmuch as I have no idea of the science involved, but I can still imagine some scenario where such valuable data becomes committed to eternal space.
