Again ;_;
Well, different people's vote contribute differently to the contribution of upvoted/downvoted person. It depends on rating (yes, CF rating) of voting person. So if you have clean account with single comment and I upvote it, but tourist downvotes it, you get negative contribution.
I also noticed that, also if you have 80+ contribution your up/downvote affect reds too if their contribution is lower than yours. Thats interesting!
It depends on rating, not contribution.
I'm not so sure about the point raised by BekzhanKassenov but I do know that downvotes on comments aren't displayed until they hit -5, to prevent herd voting / bandwagon effect. They will, however, still affect your reputation.
It's very possible that your first comment got -4 and your second comment got +1, so the net result is still negative.
It's time for some proofs :) Here's the old blog by MikeMirzayanov, but I'm not really sure if it is actual now (could not find any info about cancelling that rule).
