Clarification on what is meant with " unique on each level" for the "name" attribute of a <Terminal>

[TorstenBlochwitz]

In section 2.4.9.2.2 Terminals we wrote:

The normalized string attribute name of the element is the unique instance name of the terminal. The terminal name must be unique on each level.

Does that mean the "name" attribute must be unique w.r.t. to the list only, or does the 2nd sentence extent the uniqueness to the names of ?

I think we need a clarification here,

@TorstenBlochwitz: do you want to clarify whether in a terminal with name "foo" you can have a contained terminal with the same name "foo"?
