I don't see how the latter follows from the former? The former is much bigger and more abstract; syntax is just one of the vehicles to try and codify it.
F.ex. if you have an universal construct of green threads / fibers then 7 PLs could express it 7 different ways, yet underneath they'd all be the same.
