Another commentor pointed out that the problem they appear to be solving is consistent typesetting and layout across multiple east and southeast asian languages.
I've never dealt with those precisely but I have had to typeset documents containing both latin and greek or cyrillic (but luckily not all three) and even with that there are not very many fonts that support both, and even fewer that are a good font with both. You end up having to mix fonts, and finding ones that look good together with the same letter spacing and line height and consistent weight is quite a challenge!
I'm definitely aware of the trend of every tech company commissioning a near identical just-slightly-quirky sans serif font for no clear reason but this doesn't seem to be that.
