Property on enlargement of settlor’s interests
16.  Where property is settled by a person on himself for life, and after his death on any other persons with an ultimate reversion of an absolute interest or absolute power of disposition to the settlor, the property shall not be deemed to pass to the settlor on the death of any such other person by reason only that the settlor, being then in possession of the property as tenant for life, becomes in consequence of the death entitled to the immediate reversion or acquires an absolute power to dispose of the whole property.
