Confusing override of o-colors claret-inverse

[thurstontye]

We seem to be needing to write an override for 'claret-inverse' in our KAT app to get the o-colors value hex value because claret-inverse is being assigned the hex value of claret-2, #ff7f8a in set-user-cases.scss.

Why is this:
@include oColorsSetUseCase(topic-inversed, text, 'claret-inverse');
not:
@include oColorsSetUseCase(topic-inversed, text, 'claret-2');

and remove @include oColorsSetColor('claret-inverse', #ff7f8a);

I've probably misunderstood something but I'm a bit confused as to why this might be.
