Internet Recovery. Unlike Monterey, Sierra OS X Utilities starts with wi-fi connected, even after a nvram reset and a disk erase. How?

On boot, when I press **Shift+Option+Command+r**, a globe appears with a dropdown box to choose my ssid and password. After some time the **Sierra** Utilities starts and my wi-fi connection is enabled. This is not happening when I press **Option+Command+r** on Boot to get to the **Monterey** utilities. I get the same Globe with the dropdown box, but after the Utilities screen starts, my wi-fi is not connected, so it doesn't seems to be saved. I never inserted my wi-fi credentials on a final installation, only on the globe screen and on the Monterey utilities when I attempted an Online Recovery that I canceled. After that, I made a nvram/smc reset and formatted the disk again (disk utility > show all devices > choose the ssd disk > erase). How is this happening? Is it possible that Sierra, unlike Monterey, can get the wi-fi information from the globe part? Thanks.
