I will try to explain my position:
when we talking about riding cars, we cant talk about olmecs ( http://en.wikipedia.org/wiki/Olmec )
because olmecs disapeared a long before cars were invented
so in l2 we can talk about java-Interlude, java-Freya but not java-Prelude
and l2 is Interlude, Freya and Prelude
java represents only modern l2 not all l2
and when talking about all l2 we must remember all l2, not only modern l2
as when we talking about all human kind, we must have in mind olmecs too
