Yes, it only applies to stuff the ABC actually produces, so things like Chaser, Media Watch... Paul's new show.

Chaser and Media Watch are both "vodcast" anyway (and Paul's show may be), but this announcement means we can freely post things like screencaps or sound bites or whatever if we want to do that, so long as it's made clear where they've come from. And if things are broadcast in high-def that could mean higher quality recordings for people who miss shows and such.
I assume. Maybe the biggerwigs at the ABC will veto it but the way it was said leads me to believe that it's official ABC policy to not do anything about this. It's definitely different to the attitude of every other commercial station.
[Edit]
Also, it
might mean that since ABC was the original owner of the original series of GNW and that apparently Foxtel let their rights lapse...?
I know various people who've wanted to cap some GNW things and if official ABC policy is to not do anything about such things, we might start seeing more videos of older ABC content springing up. Maybe.
But this is all why I was clapping, if they're going to go down the route of not being asses about harmless sharing of things, we could be in for good times.
