Basically what they said is that when disputing an international contract, the defendant's jurisdiction is used by default. So if Nijisanji wanted to sue Selen for violating contract terms (like breaching an NDA or something) they would have to prosecute her in Canada. But if Selen wanted to sue Nijisanji for violating her labour rights, it would fall into japanese court jurisdiction.
Japanese civil courts are A:
notoriously corrupt
B: notoriously incompetent
C: notoriously racist.
There's next to no chance that a foreigner ever wins a case against a profitable japanese company no matter how airtight the case is. The judge will just lie their way to a dismissal to avoid needing to rule against big company and send you through a million layers of appeal processing, a process which will inevitably stonewall you because you're a disgusting filthy foreigner until you run out of money or choose to drop the case.
This is likely the very reason these contracts are so comically bad. Anycolor knows they can't reasonably enforce ANY contract terms against foreigners, but also know foreigners have basically no recourse if they're fucked over--because japan will protect the bad guy. So these contracts are more or less just elaborate extortion tools meant to browbeat the legally ignorant until they wise up and get a lawyer
