I don't agree with these changes.  You make it sound like serializability is 
an additional condition on the serializable isolation level on top of the 
no-phantom-reads condition.  I think that is not true, both mathematically 
and from the wording of the SQL standard.  It is an equivalent condition or a 
consequence, depending on how you view it.
