Dynamic area does not prioritise the nearest object. It focuses on the selected point (the center point of the dynamic area) if there is something focusable under it and if the system cannot detect something focusable in that small area, it looks for focusable things under the other points. As soon as the primary point has something under it that the system can focus on, it returns to that. There is no priority for nearer subjects (or farther ones) in the dynamic area modes.
The wide area modes have some nearest-subject priority but it is not very effectively implemented.
Hard nearest-subject priority is available on the DSLRs in group-area and custom group-area modes (D6).
My understanding was that Dynamic AF prioritizes the af point in the center of the area and then if it does not achieve focus, it ooks at surrounding AF points to try to find something to focus upon. Thus, something more contrasty in those neighboring points. Thus something proximate, i.e. larger would be more likely but not necessarily focused upon. But technically, that is correct that it doesn't prioritize proximity.
