I read that the structure in green are diode connected. I am only familiar with the single device version of diode connected MOSFET. Can you tell me what's the advantage doing it using two devices as shown? Thank you. I'm self learning please bear with me.

Cascode current mirror, specifically low voltage cascode. See e.g. Razavi, Design of Analog CMOS IC, paragraph cascode current mirrors, figure 5.13b in the 2001 edition.

As in other cases, cascode is used to increase the output impedance.
