ADB Connection or Proxy Server? (Score 1)

I remember a story just like this a year or so ago and there's even a video on YouTube about it with the "creepy conspiracy music" and everything. Now, a very critical question I had about it but of course it wasn't answered... Is he taking screenshots of the ADB Log as he has his phone plugged in? Or is he logging connections from his home router? And yes, this does matter.
