I doubt that good commands get more upvoted than before. Visible, high points serve as a signal that the comment is worth a read. Also, I believe that other things being equal people tend to upvote high-point comments more. In other words, if you did an A/B test that would (resp.) add/subtract 20 points to the displayed points of an already well upvoted comment, people seeing the high-point version would upvote it more.
