It's not a inverter any more. It's a follower, like sth in the analog circuit.

Ideally forms a buffer. But nmos is not good at passing a "1", ends up with roughly VDD-Vt instead of "1", and pmos is not good at passing a "0". Therefore won't have any practical purpose.
Also, thats the reason two inverters back to back are used to form a buffer instead of this configuration.
