It actually isn't, no.
The quoted segment is, as noted, a *relationship*; ie: a function applied
to a domain of IP addresses to produce a range of other IP addresses; it's
a *function*, and the closure applies it to produce a result.

Hence "transitive". It's not really an accident that "transit" comes
from the same root.
"The Internet" for all the purposes we generally use it here is composed
of all the machines with publicly routable IP addresses between which you
can move packets, regardless of what they're hooked to, or who they pay;
that was the point Seth made in a much more mathematical-sounding way
in his oft-quoted statement.
