I don't have Zillions, but from what I can make out looking at the source code of the ZRF, Daniel seems to be right: the brothers make camel/zebra/giraffe leaps and the nightKnight two knight leaps in independent directions. My knowledge of Zillions is alas insufficient to be able to tell whether it double‐captures (the code only tests that the intervening space doesn't contain a friendly piece, which suggests it might?) or whether it implicitly forbids null moves (no explicit check seems to be made).
For what it's worth, “two out and one over” seems to be a semi‐common way of describing the knight's move
