Question Ladder Paradox question

If you have an observer carrying the ladder at it's back then he will say that the front of the ladder crashes into the back wall of the garage when he is already inside the garage because the light needs some time to travel from the wall to the observer. So he will agree with a stationary observer (stationary relative to the garage) that the ladder was compleatly inside the garage at some moment in time.
But what if you have an observer carrying the ladder at the front and he looks behind himself at the instance he hits the back wall. What will he see?
He should see the ladder already being inside the garage because otherwise he would disagree with the previous observer (who is not moving relative to him), which is impossible.
