I guess I'm not quite sure what you're asking... but the MediaWiki poll coding treats each individual 'Yes' option as a unique option. So, the poll records the fact that two votes have been placed, one on the first option, and one on the second option, but is unable to recognize that they were, in essence, votes for the same option: 'Yes'.

Hope this answers your question; if not, please tell me.
