On container :

gab at dahlia ➤➤ ~ % ip addr
2: host0: <BROADCAST,ALLMULTI,AUTOMEDIA,UP,LOWER_UP> mtu 1500 qdisc
pfifo_fast state UP group default qlen 1000
    link/ether 56:84:f7:39:43:c7 brd ff:ff:ff:ff:ff:ff
    inet 192.168.1.94/24 brd 192.168.1.255 scope global host0
       valid_lft forever preferred_lft forever
    inet6 fe80::5484:f7ff:fe39:43c7/64 scope link
       valid_lft forever preferred_lft forever

gab at dahlia ➤➤ ~ # ip link set dev host0 down
gab at dahlia ➤➤ ~ % ip addr
2: host0: <BROADCAST,ALLMULTI,AUTOMEDIA> mtu 1500 qdisc pfifo_fast
state DOWN group default qlen 1000
    link/ether 56:84:f7:39:43:c7 brd ff:ff:ff:ff:ff:ff
    inet 192.168.1.94/24 brd 192.168.1.255 scope global host0
       valid_lft forever preferred_lft forever

Now looking on host :
gabx at hortensia ➤➤ ~ % ip addr
4: vb-dahlia: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc
pfifo_fast master br0 state DOWN group default qlen 1000
    link/ether 8e:a4:c3:8c:cc:89 brd ff:ff:ff:ff:ff:ff
    inet 192.168.1.94/24 brd 192.168.1.255 scope global vb-dahlia
       valid_lft forever preferred_lft forever
    inet6 fe80::8ca4:c3ff:fe8c:cc89/64 scope link
       valid_lft forever preferred_lft forever


It was UP before I brought vb down. So you have your answer : yes.
