The rules stated for deletion of a post are left vague, and I think they need to be that way. There is no telling what someone might post and leaving some leeway for the powers that be to moderate this is not a bad thing. I have not seen any evidence of this being abused. I would suppose that if in the event that a post did get deleted that all of the replies would be deleted as well; but certainly the authors of the replies should not be penalized as the author of the original post would be. Unless of course the reply deserved such based on its own merits.
