I'm not sure about that. We are talking about sub-cooled LOX here. My 
understanding is that it is sub-cooled before being pumped into the 
tank. If you pump sub-cooled LOX into a tank the drop in pressure as it 
enters the tank doesn't have to be significant, and it is gases (or 
plasmas) that drop in temperature when the pressure drops. Liquids, not 
so much.
