It's on line 23-24 of the linked email's body.

As I wrote, this is the problem:

This means that if you customize completion-styles, you also need
to tweak completion-category-defaults, because the latter shadows
the former. Stefan thinks this is a bug, and so do I.

Moreover, Stefan has stated that you need to "constantly" tweak
completion-category-defaults because other packages might
add to it.

I haven't analyzed the problem sufficiently to tell you _why_ the
shadowing happens, just that it happens.
