I don't know what org-with-point-at and org-fold-folded-p do, but my
point is that you should consider the case when kill-line kills
invisible text that has nothing to do with Org's headings and trees,
so I suggest to either make the detection code smarter (so it could
distinguish between the two), or make the prompt text vaguer (to not
claim that the text must be a subtree).

And if that is still not clear or you disagree, let's leave it at
that.
