Is this different per theme? Does that mean that it wouldn't pick up custom OEM
colours/settings?

The v21 suffix in the directory is for the API version in which material design
was introduced. I'm not sure yet how OEM themes modify the parent styles used
here.

See this article for the available qualifiers and how they are applied:

     <!-- Theme variation for low-end devices.
 
         Since ChromeActivities are not HW accelerated, they don't get fancy
         material shadows for popups. This theme sets drawable with pre-baked
         shadows to those popups to make them look better.
         'popup_background_shadow' is a copy of 'abc_popup_background_mtrl_mult'
