Is name:ko compatible with name in Korean map?

I try to remove a "name:ko" key whose value equate to value of a "name" key. An example: name=서울역, name:en=Seoul Station, name:ko=서울역

In OSM, I wonder if "name" having Korean value and "name:ko" each have different role. I've thought that they are equatability because a feature's name is basically printed to a value of "name" key having a Korean value, that equates a role of "name:ko".

I'm sorry about my English writing skill.
