When you attach a recovery email to a Google account, any major security change—password resets, app password removals, suspicious sign-ins—triggers a notification to that secondary address. It functions like a canary in a coal mine: if an alert shows up that you did not generate, your primary account may be in someone else's hands. Many users skip this setup entirely and lose the only out-of-band signal that a breach has occurred.
