I'm not sure you fully understood the question.

To use the same vocabulary with both the S-A and S-B idioms is, per
my understanding, to use it in conflicting ways.

One should be able to merge graphs where folks have employed the same
vocabulary, regardless of idiom used, without concern for conflict.

If they can't do that, then either they can't use both idioms freely
or they need to vocabularies.

Right?
