his failure to dispel the possibility of a lapse and other possibilities where these are more apparent, and his departure from wording that would unequivocally exclude a lapse in every case, in favour of wording that more clearly indicates a restriction than merely excludes a lapse in certain cases, are conclusive evidence that this was not what he intended.
A parallel would be a man saying to his slave: “Honour Zayd. If he is righteous, honour him.” Zayd is not righteous, so the servant does not honour him. His master then says to him: “You have disobeyed my command. Did I not order you to honour him?”

Had you intended the command to apply generally, you should have said: ‘Honour him even if he is not righteous,’ since honouring a righteous person would then follow all the more clearly; or: ‘Honour him even if he is righteous,’ if he is truly dear to you.”

When asked, “Why, then, did he qualify the transfer by saying: ‘Provided that, if any of them dies leaving no child, his share shall pass to the members of the tier’?” he replies: “To exclude the possibility of a lapse in this case, but not in the case in which there is even greater reason to exclude it.”
He may then be told: “The wording would have been
