I doubt it. Roan just realized that his plan failed, and that Clarke wasn't going to kill Lexa. Probably once Clarke walked into the room all dressed up for the ceremony he knew she wouldn't go through with it. Also, Roan most likely knew that Clarke would be freed for bowing before the Commander. Maybe he thought that if he bowed, he would be free, too.
