LOX load starts on the first stage, Stage 2 begins receiving oxidizer just inside T-30 minutes. # Falcon9

Ну уж этот момент они отработали и минимизировали риски.
Маск говорил, что предстартовая циклограмма еще сырая, и тут, имхо, он имел ввиду интеграцию РН с новым стартовым комплексом. Вот тут может что то всплыть. Но Маск же на пуске ))
