If you don't remove your device from your Apple ID account then no one can use your device, ever.
Don'ts
If you remove the device from your account after you erase it, Activation Lock will be turned off. This allows another person to turn on and use your device.
An example of my iPhone 5 is given in the GIF below. There is no "Undo" after you remove it from your account.
