The illustration in Vision Age #4 differs from the one on your link as well.  
The right side of the meter window on top has three symbols -- at the rear a 
red circle, in the middle a yellow semicircle, at
the top a black box with a "-" through it, whatever those mean.  I suppose 
"full sun", "half-sun", and "low light"?

To quote the relevant portion of the article verbatim (pay particular attention 
to paragraph 4):

PERFECT LIGHT VALUE
In 1958, Olympus announced one more pioneering high-performance 35mm lens 
shutter camera.  This was the Olympus Auto.  First, let's take a look at its 
highly individual design.

The top of the camera is dominated by the light meter and the viewfinder, with 
the rewind crank relegated to the camera bottom.  The explanation is that the 
designers wanted to lengthen the base length of
the rangefinder and get the maximum possible viewfinder magnification in order 
to fully exploit the fine performance of the newly developed 42mm F1.8 G Zuiko 
lens.

At that time, Olympus gave the new camera's exposure meter system the title of 
"Perfect Light Value System."  In justification, we should point out that the 
camera's exposure selection system permitted a
free choice between aperture preferred and shutter speed preferred, what is now 
known as a programmed exposure system.  In other words, at a time when people 
were still bumbling along with awkward linked
exposure meter and shutter systems, Olympus offered the generous choice of 
setting either the aperture or the shutter as desired.  After that it was 
merely a question of aligning the moving indicator line
with the meter exposure indication in order to be sure the exposure would be 
all right.  Furthermore, when extreme lighting conditions rendered the initial 
aperture or shutter speed settings unsuitable,
there were automatically corrected to ensure a perfect exposure.

"Perfect" was clearly more than just the usual advertising hype.  There is not 
space here to go into a detailed explanation of the newly developed mechanism 
adopted in the construction.  Suffice it to say
that when the shutter speed dial was rotated, the aperture was also changed in 
order to maintain the same light value, but when the aperture dial was rotated, 
only the aperture setting was changed.  In fact,
the Olympus Auto was then the only coupled exposure meter-type camera in the 
world with this kind of versatility.  But the spirit of the times was drawn 
more to developing a simple, basic type of exposure
automation rather than pursuing this kind of perfect picture-taking technology. 
 Consequently the ambitious Olympus Auto was unavoidably discontinued only a 
year after its first appearance."

The article also contains a box titled "Olympus Auto Specifications", which 
notes that the camera has an intentional multiple exposure mechanism -- I 
suspect that the slide under the wind lever activates
this function.  This mechanism may be damaged, causing the wind problems you 
note, though if the camera is similar to many of the era, the fault may lie 
inside the bottom cover.  If it is like cameras like
the SP, etc, there is a large clutch gear and arm inside the bottom, and a 
winding crank, either on which may have come loose.  Unless the rewind 
mechanism is in the way, you might want to try opening it to
check for loose parts.
