Hidden in a footnote at the bottom of Page 108:

"When shooting with the intermediate range (focal length) of a zoom lens, the AF's point of focus is corrected relative to the adjustments made for the wide-angle and telephoto ends. Even if only the wide-angle or telephoto end has been adjusted, a correction will be made automatically for the intermediate range."

If you look at the EXIF info when shooting in the midrange, you'll see that an intermediate MFA value was used.
