It's also my understanding.
I applied in Meta for merit source position because I felt that we don't have enough MS in our local board, Croatian.
I even have topic there where local users can report their good quality posts for merits https://bitcointalksearch.org/topic/zbirni-topic-za-davanje-merita-za-kvalitetne-postove-i-za-korisne-informacije-4265795
But, if you check reported or suggested posts you will realize that a lot posts are from English part of the forum, mostly scam warnings.
I don't have time to read all forum so in such way I can find and reward good quality posts with merits.
I also reward other good quality posts from non Croatian members.
