Confirmed. 

I wonder if anyone ever tried a Tetramic at the focal point of
a parabolic reflector (the Z-axis aligned with the direction
pointed to). Then if you keep the e.g. X-axis horizontal and
decode to a virtual stereo mic, you should get an 'enlarged
stereo' of the remote sound. 

Given its small size, the Core Sound Tetramic should be ideal
for such a setup.

The same thing is routinely done with radio waves - some large
parabolic antennas used for satellite reception have outputs
equivalent to W,X,Y, with the latter two used to make the antenna
track the source (by a servo loop that tries to maintain zero X
and Y, using W as the phase reference).
