Back when I used an automated vote counter (which is broken nowadays but could possibly be fixed again?), it pointed out votes to the mod, but asked the mod to manually specify who the vote was for if it was at all unsure (i.e. not an exact match). You could add name synonyms to it manually if you wanted to, but I rarely bothered.
The main benefits were in preventing missed votes, preventing accidental reversing of votes (when player A votes for player B, it's really easy to accidentally put that on your vote count as player B voting for player A), and formatting the vote count appropriately (with links and the like, as it doesn't cost much for an automated counter to add them).
