Let's take another absurd example.  You are listening to two talkers
through a *single* loudspeaker.  You would almost never think they were
one speaker, even though the angle of separation is zero.  Spatial
separation is useful, but is far from the defining feature of stream
segregation, for the simple fact that in highly reverberant environment,
the necessary information (time of arrival, phase)  can often be
ambiguous.
