"Left baseline alignment" and "Right baseline alignment" ...?

Being able to align text baselines in an Auto Layout is fantastic, and it got me curious about the purpose of “Left baseline alignment” and “Right baseline alignment”. The only use of these I can imagine relates to Asian typography – specifically tate-chu-yoko & warichu. (full disclosure: I designed those features for Illustrator CS back in the day)

Am I missing another reason for these? There’s no documentation about it that I can find, so now I’m wondering if there’s other use cases. It’s also a curious choice to me to see them visible on the grid widget yet not in Advanced Layout options.
