This is for those rare instances where manga (Japanese comics) are written left-to-right (frame and balloon order, text orientation) for whatever reason. Note that Korean comics are usually read left-to-right like Western comics.
May also apply to not-so-manga posts, for distinction among their paneled brethren. Does not apply to any comics that are mainly written in a language that's meant to be read from left-to-right. (e.g. English, Russian, Thai)
