The son's sale only becomes valid after his father dies, when he inherits it - even in the grave, and he then passes it on to his children or, as in this case, to the purchasers.
The reason that he is able to sell it in advance is because, already in his father's Lifetime, he is an heir who stands to inherit it automatically when his father dies
