Sorry for devil’s advocate here because I agree with you but hypothetically the answer would be verification. ie., Google already has your password, so why would they need to ask you for it when you log in?
Clear Blue is like this, but they use your iris scan. You have to scan every time to skip the line. But the TSA precheck just fingerprints you once when you sign up IIRC
