One of the heirs is not included in 'class I heirs' under the Hindu Succession (Amendment) Act, 2005?

The Schedule to the Hindu Succession Act, 1956, as amended in 2005, adds descendants through pre-deceased daughters such as the "Daughter of a predeceased daughter of a pre-deceased daughter", the "Daughter of a pre-deceased son of a pre-deceased daughter" and the "Son of a pre-deceased daughter of a pre-deceased daughter" to Class I, but the "Son of a pre-deceased son of a pre-deceased daughter" is not included.
