That depends on what "better" means. If better means actually winning in Jeopardy, then two games is not enough. Final Jeopardy plays a significant role in who wins a game, so it's not just like combining multiple games into one. Even on the question level, a disclaimer should be given if Watson doesn't answer enough questions for statistical significance. Finally, the issue here is with contributing to the statistical ignorance of people watching the two game match. Sure, Watson has played many games already before the match but that's not what's being shown on TV.
