A very good question.

I'd need to spend some time checking my implementation to answer that 
(w.r.t. my implementation, of course).

I did notice that there is a weakness (==bug, I think) in some aspects of 
my inference engine implementation that I cannot "scope" bnodes to be local 
to a formula, or global.  I think there are situations where eithe5r is 
required.  That suggests to me that a comprehensive implementation would 
support both bnodes local to a formula, and also "exported" to a containing 
formula.  Which in turn suggests an extension to the model.
