Notice how little she glides at the front of her 400m stroke. Notice that her tempo is 80-85 SPM.
Here's a transcript of the video commentary starting at 10:35:
[Mark Schubert] Lindsay uses a 2-beat kick for the 400; she has a higher tempo; her arms are at a higher stroke rate. 2 kicks per cycle.
[Lindsay Benko] When I use a 2-beat kick my arm tempo is a little bit faster than when I'm using a 6-beat kick, so i'm relying more on my arms.
