The draw by stalemate looks like a spot of discontinuity in the otherwise harmonious universe of values. To save a game by letting yourself be so completely humiliated as not being able to make a move looks rather undeserved.

Finally the novelty came. These days it seems to be normal to play novelties somewhere in the ending. Apart from just being the novelty, this move is also very strong. It is most probably that Radjabov found this natural improvement over the board, as he spend more than an hour, if I am not mistaken. But it could be that he was just trying to remember his own analysis (can you imagine how much he has to remember??).
