That's just the way that the game was programmed. When you enter Snowdin and start killing monsters, if you check at the SAVE points you may notice the message that says "That comedian..." If you fail to kill Snowdrake before exhausting the kill counter, the message will change to "The comedian got away," and you will be shunted onto the Neutral Route.

Why Snowdrake specifically, though? I have no idea. You'd have to ask Toby that.
