Primary text
There are two perspectives on whether the follower's prayer is invalidated in this specific scenario. One opinion states that the follower's prayer is invalidated because the follower intentionally omitted an obligatory act of the prayer, paralleling the invalidation caused by omitting the first Tashahhud.

The second view maintains that the follower's prayer is not invalidated because nothing remains of the prayer except the concluding Salam (greeting).
