I believe you missed shep's words immediately above, which were, "for example"

Let's see what pkg_info(1) can tell us about these two applications. On this workstation I am using, both are installed, and they are installed because other applications depend upon them, as noted in the output.

$ pkg_info dbus

Description:
D-Bus is a message bus system, a simple way for applications to talk to
one another. In addition to interprocess communication (IPC), D-Bus
helps coordinate process lifecycle; it makes it simple and reliable to
code a "single instance" application or daemon, and to launch
applications and daemons on demand when their services are needed.

Description:
Avahi is a free, standards-compliant implementation of the Zeroconf
protocols Multicast DNS and DNS-SD.

It is a system which facilitates service discovery on a local network.
This means that you can plug your laptop or computer into a network and
instantly be able to view other people who you can chat with, find
printers to print to or find files being shared.  This kind of
technology is already found in Apple MacOS X (branded Rendezvous,
Bonjour and sometimes Zeroconf) and is very convenient.
