Is That Mistaken Dialogue in 'Rebel'?

Some of  the audiences who watched the movie 'Rebel' could not understand some of the dialogues in the movie. Especially, they confused with one of the dialogues in the movie and it goes on like this; 'NENU YAMUDI ROOPAM LO VACHCHINA  Rebel'. Surprisingly, Prabhas has not come in the get up of lord Yama in that seen. Then why has he uttered that dialogue? 

Some of the sensible audiences are expecting that the dialogue writer, perhaps, confused in writing the dialogue and Prabhas uttered the same dialogue.  As per them, the dialogue should be like this; 'NENU Rebel ROOPAM LO VACHCHINA YAMUDNI.' Is this right? Only the dialogue writer knows the facts.
