There may be an outer subject with no inner subject:

The clausal counterpart of this relation is csubj:outer.

Only subjects are required to be distinguished in this way. There may, for example, be inner and outer copulas, both attaching as cop:

The :outer subtype is not intended for most nominal subjects of copular clauses—only those where the predicate is itself a clause. Plain nsubj (or another subtype) will be appropriate if the copular clause predicate is a nominal, adjective, etc.:
