Re: [csswg-drafts] [css-mixins-1] Behavior for multiple `@result` rules (#13522)

The current spec wording is:

> A [mixin](https://drafts.csswg.org/css-mixins/#mixin) can contain multiple [`@result`](https://drafts.csswg.org/css-mixins/#result-rule) rules, and all of them are concatenated, in order, to form the [mixin result](https://drafts.csswg.org/css-mixins/#mixin-result). `@result` rules inside of false [conditional group rules](https://drafts.csswg.org/css-conditional-3/#conditional-group-rule) are not included in the mixin result.

Which seems to cover @kizu's use case without the potentially destructive last-one-wins behavior. What am I missing?
