Why does lowering the temperature of the gas flowing into the expander actually result in a decrease in high-pressure pressure?

I looked at this problem but couldn’t understand it for a long time. Thank you, friend, for helping me explain it in detail?
Firstly, your expander features intermediate heat exchange, which means it relates to the cold zone of your plate exchanger. The lower the temperature in this cold zone, the easier it is for air to liquefy – that’s how it works. However, the temperature cannot be reduced that much!
Reply to 1# Wu Zhijun: One of the functions of an expander is to create a pressure drop in the gas, thereby reducing its temperature. It is normal for the overall cooling pressure of the gas to decrease as well.
