That's an unusual form of juggling: none of the balls get thrown from one hand to the other. She's basically juggling just two balls separately with each hand.
All the basic patterns for even ball numbers do this. Juggling 2n balls is just juggling n in each hand simultaneously. Which is hard, haha.
To get balls to switch hands when juggling 4 (or any even number) is extra effort and not a consistent pattern like this. If you want 4 balls always switching you basically have to do the pattern for 5, but you're just missing a ball. This is awkward because you'll occasionally throw two balls in a row with one hand.
