well, there was a horizontal line and off from that broke the basic
networks (.com .mil .gov etc) in vertical directions (some up, some
down).  Each "T" in the network was a further sub net (so, when
the .edu broke off the base line, there were further breakoffs
to .gatech and .mit and .berkeley etc)

I think they put commercial orgs on .com even if they had an additional
 .mil address..  it wasn't meant to be a geographic map (from what I saw)
but a network topology map.

hope that explains it..if I find a copy, I'll send it to you.
