I'm confused by your reply. The grandparent comment was saying "You should never flip a coin", the person you replied to said (roughly) "It's impossible to avoid all situations where you can't measure the winner, you have to either flip a coin or just take the person who happened to come out ahead in the vote count".
Your link to a place where they used a coin flip isn't disagreeing with him (nor really the grandparent, who wasn't claiming that you can't use a coinflip, but rather that you shouldn't use a coinflip).
