If you set them all up at one time, in one environment, they’ll all be part of the same Sonos Household. Then when you took the “other” set to the other environment, they’d share essentially the same thing….until you made a change. When they’re separated like that, they’re no longer maintaining the same playlists, streams, etc. Sonos doesn’t store data in the cloud, so they’d eventually drift apart, while still being associated with the same “account”. 

Note that if you set them all up in one place, moving them to the second place would be a lot easier if both were either wired (Sonos BOOST or a Sonos speaker) or shared the same SSID/password in both locations.
