can someone please tell me how did they derive with the above equation?

my point of view:

Vgs = Vin

Vds = Vout

so how did they even get Vgs = Vds?

below shows the Small signal circuit:

might be a stupid question to ask. but i am really confuse on when to look at the original circuit, when to look at the AC circuit, when do i remove the load, etc.

Thanks for helping and sorry for asking such a simple question here.
