All addresses that are displayed on "Addresses" tab are yours and are backed up by your seed phrase (+ passphrase, if there's any). Take note that you will receive the fund even if you use one of the addresses labeled as change.
And there is no hidden (auto-)refresh of the available green addresses. All green addresses are hard linked to my wallet
and stay alive until I use them.
I am not sure I am understanding you correctly.
Your seed phrase always generates the same addresses and you can use any of your addresses as many times as you want.
