Wow, that was totally unexpected! Thinking back (circa 2013), I wonder what video quality lessons he got out of that particular set-up. From what I recall, we had something awful:

1) Presenter computer plugged into some sort of video capture hub, connected to computer A with video capture card that would composite camera video with slides. 2) Separate computer B running remote desktop into that computer to broadcast to the web. 3) Another computer C, also with remote desktop, connected to the projectors.

Serious productions bring all video signals into a switcher [0] and compose their outputs to screens/projectors/capture devices from there. You can tell something like this is in use if there are sensible transitions between different presenters' computers, and the audience doesn't have to watch the resolution-negotiation phase.
