보스니아 리그는 승강제가 어떻게 되는 거지

https://en.wikipedia.org/wiki/Bosnia_and_Herzegovina_football_league_system

The second tier is divided into two leagues – the First League of the Federation of Bosnia and Herzegovina and the First League of the Republika Srpska – containing, respectively, 16 and 10 clubs. Relegated teams from the Premier League are demoted to the second-level competition in the next season. Geographical location is the criterion for decided decision in which one of these two leagues the teams will play. The winner of each league is promoted to the Premier League, and the bottom teams are relegated. The number of relegated teams depends on how many teams enter from the Premier League and the Third Divisions.

대충 2부 리그가 정치적인 이유로 보슈냐크 무슬림+크로아티아계 리그와 세르비아계 리그로 나뉘어져 있는 건 아는데

저 글대로라면 강등될 땐 자기 소속 지역 리그로 가고 승격은 양쪽 우승팀 하나씩인데

그러면 한쪽 지역에서만 2팀 강등되면 어찌되는 거지
