When a snap is first posted, it'll have a little bar graph thing on the right. A fresh snap with no votes yet looks like this. As people vote on it, the snap keeps track of where those votes come from - if someone sees the snap while browsing their front page, the vote will be added to that bar. If someone downvotes from /t/music, the /t/music bar will decrease. See screenshot of rothelys snap here. This shows that most of his upvotes came from people viewing his snap from their front page or live feed. The empty /t/music bar shows that someone downvoted it on the /t/music page.
Note: this also affects how the vote counts are displayed. For instance, I have a music video snap that has received two upvotes, screenshot here. However, it didn't receive any of those upvotes from /t/music, so when you go to the /t/music page it doesn't show that it has received any upvotes because within the music tribe, it hasn't. Screenshot here.
