Jim,

     Or maybe your exposure to stereographs has trained your depth 
perception, while the untrained depth perception of "people with normal 
stereo vision" is simply new to the medium.

    When I first started making print stereographs I was struck by the 
cardboard cutout quality of people and objects in my pictures.  With time 
and exposure that quality disappeared, replaced by greater realism.  Then 
I left off print stereographs and started making slides.  After a few 
months away from print stereographs I took them up again -- and the 
cutout quality had returned.  Now, with pracitce, it's gone again. Other 
people, looking at my print stereos for the first time, often comment on 
their cutout quality.  

   The brain has to learn to look at stereo images, and, in my example, 
gets more accurate with time.  I bet that's what's happening in your eye 
guy's office.
