I don’t believe they were using cryogenic propellant in the first stage yet. They were preparing for it just before this.

You might be confusing cryogenic with subcooling - it is still cryogenic (or it would not fit into the tanks at any reasonable pressure), just colder and more dense (you can fit it a bit more than if its at a higher, still cryogenic temperature).
