Hello,
For faint extended objects that are more difficult to detect, the algorithm maximizes contrast, but for obvious or easy objects, contrast doesn't really matter, so it attempts to pick the eyepiece that presents the most pleasing view, which depends on the size of the object. A small planetary will look better with higher magnification, but a large one may require a wider field of view to fit.
In your case of the two similar magnifications, the eyepieces are probably not truly identical. For example, the exit pupil may be different. So the algorithm is picking the one that optimizes contrast or field of view, although in practice there may be little difference.
