Honestly, I'm surprised that Beory made it into the Top 10, let alone the #4 slot. She was one of the gods that didn't make it into the 3E PHB, so I expected lots of "I don't even know who you are LOL" posts and downvotes. But I'm happy to see her finish strong, even if she didn't win...she's one of the better deities of Greyhawk, imo.
Nope...in fact, that very situation is why splitting your downvote isn't allowed.
It's a feature, not a bug!
EDIT: I see that I misunderstood your post. (This is what I get for multitasking.) If it comes to pass in the manner you describe, the order of the posts would determine the winner. Which is also a feature!
