XPS or No....I noticed this

I have been struggling with weather or not to use XPS. I was in my Dad's 22 year old 4 star energy efficient PPL home with finished basement an noticed that his poured concrete walls were insulated as follows:

Pourced Concrete Wall, Plastic Sheet directly against that, white 1/2" styrafoam against that. Thats it! He does have a section drywalled. I assume they just studded in front of the foam. I found the plastic in between the foam and concrete interesting.

Of course the styrafoam of 22 years ago is likely different than the XPS of today.

It seems the methods are always changing.
