It doesn't list containers under your home dir.  However if you create
a root-owned  unprivileged root-owned container, lxc-autostart will list
it:

cat > lxc.conf << EOF
lxc.network.type = veth
lxc.network.link = lxcbr0
lxc.id_map = u 0 100000 100000
lxc.id_map = g 0 100000 100000
lxc.aa_profile = lxc-container-default-with-nesting
lxc.start.auto = 1
lxc.mount.auto = cgroup
EOF
sudo lxc-create -t download -n listme1 -f lxc.conf

After this, 
	sudo lxc-autostart -L
should show
	listme1 0
