I think you're looking at this:

[ "$BRIDGE_HOTPLUG" = "no" ] && exit 0

?

Just before that is:

[ -f /etc/default/bridge-utils ] && . /etc/default/bridge-utils

and /etc/default/bridge-utils sets BRIDGE_HOTPLUG, which is by
default:

# Shoud we add the ports of a bridge to the bridge when they are
# hotplugged?
BRIDGE_HOTPLUG=no

and... none of this seems documented. Not in
/usr/share/doc/bridge-utils/README.Debian and not in the
bridge-utils-interfaces(5) man page. This is all a bit rubbish,
really.
