That's what I had guessed but can you elaborate on this instance merge?

I had the feeling that the context node in the master form was becoming
the instance of the subform, is that what you mean?

Couldn't subform-instance() and subform-context() be pointers to the
subform default instance and context node without changing the behaviour
of this "merge"?

Sounds impressive...
