I think it does matter in a way that the writers who try to ground their story in common sense and realistic expectations tend to also write rounded characters and coherent story line. Of course its not always true but it is generally true. Also it helps to keep our suspension of disbelief intact.
Of course your point of view also makes sense given how Yaoi are usually written.
