Great decision! However, be careful - although they formally don't mind but they can flag the second account for being a puppet account. Two diff laguanges is a good way to border one from another... Sufficient way? Who knows.

triggering reach limitations

Or better to say reach canceling. Threads did to my 2 accounts when I logged in for both on my mobile. They sent me a letter "A login on a new device, your accounts can't be" that and this "for safety reasons" and at the same time I lost all vistirors/likes/etc apart from the followers. After 2 days of suffering :D, I deleted the app from my phone and everything recovered for both accounts.

Just keep in mind.... Threads is a new app, with AI with potentially contradictory behavior.
