What's new about it? I saw nothing novel in his suggestion.

Mutative operations perhaps but we are discussing transactions. Transactions comprise multiple mutative operations that must complete as if atomic or must not happen at all. In a distributed system, a transaction may alter state in different distributed components and still exhibit apparent atomiticity.

I suggest to you what I suggested to David: open any book on transactions and catch a clue about the prior work.
