One of the Facebook configuration features has the following label: "If you don't want a Facebook account after you pass away, you can request to have your account permanently deleted."
My friend claims that this phrase is ambiguous, with one possible interpretation implying that one can have worldly wishes after death, i.e. "after you pass away you can request X" or "after you pass away you may decide that you don't want X" are semantically equivalent to the given phrase or parts of it (which he finds hilarious for this reason).
Is it possible? Can this phrase be interpreted semantically in such a ridiculous way in terms of grammar? Or, perhaps, it should use different tenses to warrant such an interpretation, e.g. "If you don't want a Facebook account after you [had] passed away..."
