Yes it does. There are multiple states a slot can be in anyway, so
trying to treat it as a boolean won't work. For a down node, you get
an empty response. If you're simply trying to test if a node is in a
pool or not, you can do something like this (bash)

status=`condor_status -format "%s\n" State $machine`

if [ $status ]; then
  # do whatever you'd do if the host is up
else
  # do whatever you'd do if the host is down
fi

One thing to note is that if a host has multiple slots, you'll get
multiple output (with the specific format example, you'll have a line
per slot). If you want to do anything more than a simple comparison as
above, you should either specify slot1@$machine or use head or tail to
get only a single line of output.
