I've not tried recently, but I seem to recall from past experience that it doesn't. Why not just try? Use your FTP example, start an FTP connection, prohibit the "master" FTP connection and see what happens to the related connections? It may not be the answer you want, but one way around this might be to flush the conntrack table (conntrack -F) at the relevant point in time.
