I'm not really just talking about the current rule, though. Loads and loads and loads of people felt it was a deliberate handball by Kewell. Check back through the match thread, if you had all the Aussies on ignore then a massive majority felt it was intentional by Kewell. So I don't see how you can say they were different. One guy stopped the ball with his hand to stop a goal....and so did the other.
Again, if you don't think it was intentional then yess they are different, but otherwise it's nothing to do with application of rules.
