Teams meeting policies - store recordings outside of your country

Hi, 

There is a new setting under Teams Meeting policies that I'm not sure what it's for. Under recording & Transcription section, the setting is "Store recordings outside of your country or region". The only documentation I could find about this is just how to set it but doesn't explain why is this a setting? What is the purpose of that? why would we turn this on?
