> 508 and WCAG 2.0 as "if the only thing said is what's on the screen, then they can act as the captions.

As long as they are synchronized you have a case to argue. If you had a whole screen of text rather than a line or two at a time then it might be harder to argue that they are synchronized with other visuals going on. How far you could push having a large amount of text might be a discussion point.

I've also run into these situations where you have animations with audio and the text on-screen. People often ask if the audio is sufficient or if the images in the animations need to have alternatives. While non-text must have alternatives -- if the non-text content is part of time-based media it only needs a description as the audio or audio description in the time-based media can act as the media alternative. But certainly this is a fine line to walk when animations have stop and start buttons and it may be preferable for people who are Deafblind to read the text in Braille with their screen readers as audio and captions are likely not accessible to them (unless the captions are accessible non-embedded text and it is easier to step through them).
