To some extent it probably does, but the more witnesses you choose, the less your vote means.
You have 1 million HP (let's assume that would be the case on Hive). By choosing 1 witness you give him 1 million HP vote, but two - only 0.5m. So in assumptions you should focus on a couple of witnesses who are really good.
