please read the email as a whole, and don't just jump on one opening sentence.

The order in which they go is defined in the node tree.
And the in-/outputs do not change within one processing cycle.

One synthdef is not dependent on others, once it has its turn of being 
processed. At that moment it takes the data from its input buses, and 
produces output on its output buses.

So given that the dependencies are known within each process cycle, some of it 
can be parallellised, I imagine. Of course depending on the complexity of the 
node tree, and how intertwined the different synths are.

The final mixing stage may have to happen on one CPU, depending on how the 
audio driver works.
