I think it means that the button text must meet the relevant contrast requirement when active (clickable), but is then exempt once it becomes inactive.
My assumption is that they did this on purpose because "graying out" is a very common practice when things are inactive.

Subject: Inactive UI components and WCAG 2 compliance
Greg and I were having a conversation in the IRC channel about WCAG compliance and inactive/disabled UI components. According to the WCAG guideline, it states:
"Text or images of text that are part of an inactive user interface component, that are pure decoration, that are not visible to anyone, or that are part of a picture that contains significant other visual content, have no contrast requirement."
In the context of a button that is active and then becomes inactive when activated (i.e. a Submit button that is enabled until pressed), how should we interpret this guideline? It seems the *act* of becoming inactive is significant (this merits contrast?), however, the guideline states that the contrast requirement doesn't apply to inactive components. How should we handle contrast styling in this case?
