I put a AA battery on a table, the 77mm Limited, then I focused the far background. After this I tried to focus on the battery with the two focus modes putting the battery outside the central point, in both cases the camera has focused when the battery was between the central point and the nearest one
There are some evidence that the statement on RICOH site are correct even if doing some tests the two modes look the same.
Canon has a similar feature, there is a "SEL" like mode but you can choose two AF points size.
