That's not always true. The only votes they show before they are counted are ones that are not in question based on the strategy talking we've been shown through the episode. That's the only common thread through every tribal. If they've set up any doubt about how someone will vote, they won't show it. That USUALLY corresponds to them showing the person being voted out writing their vote, because it's usually very obvious who the person being voted out is going to vote for. But it's not a universal rule. The only universal rule is that they only show votes that don't give us any new information about which way the tally is going to fall before the votes are read.
