the same happened when i had a colleague over for a listening session of
a jazz tune that was done with the musicians around a tetramic (with
second-order spots). he was able to comfortably locate all instruments
except the double bass (which was at 180°). i encouraged him to turn
around a bit, and reported stable localisation after the initial
"homing-in" process, too.
Not, of course, wholly unexpected, since since this is the same mechanism
we use "in the wild" to resolve any degree of ambiguity in natural
acoustics. We see (or, rather, hear) which cues change in a manner
consistent with the movement and disregard (or, at least, down grade the
importance of) those that don't. It's one of the pitfalls of
non-headtracked binaural that this doesn't happen.
