The problem with Steven's art (aikido) is that it's based more on redirecting your opponent's energy against him (kind of in the way Judo does) thus against Van Damme, a seasoned Karate vet with a good offense, it wouldn't have done much. Most guy who do aikido wait for the other guy to attack them, they have no real offensive movements themselves. So unless Van Damme had charged Seagal like a running bull, Seagal wouldn't really have been able to do shit.
