It *does* wait[1] -- it just would continue doing the second part regardless
of the exit status of the first. So if the ifdown part exits with nonzero
(most probably signaling an error), the ifup part would be tried nevertheless.

you really want the second, third... command executed in any case. Then
the semicolon would be The Right Thing [TM]

sleep 10 ; echo "good morning"
