I see what you're saying (although even with my delay off my D810 doesn't seem to adjust focus like that on a regular basis). This is just a micro adjacent of the focus, not an attempt at an AF point switch.
However, that's not what I was referring to in the post - I think we're talking about two different things. What I'm saying in the post is that the D810 will lock on and stick with the subject, never going back to the primary point.
I just tested again to verify... irregardless of the specific delay setting on the D810 (and other earlier Nikons) it will eventually time out and revert to the original AF point even if the original focus area has not been lost (I used the normal setting to verify).
But an interesting point to note is that when in a dynamic mode the selected AF point is actually functioning in a "group mode" fashion and it will focus using any of the AF points immediately around the selected one. In order to see the AF shift/revert you may need to get the original point of focus away from the central 9 AF (surrounding 8) points.
In my testing the D5 also seems to be using the selected AF point in group mode... but the points are much tighter together.
EDIT:
There may be something more to it w/ the older bodies than I previously thought... On further testing I can get it to frequently/repeatedly shift focus w/o moving the initial focus area/subject out of the focus zone, but I can not get it to do it consistently at a given time interval. It may have something to do with how easily the two areas are focused and cross type focus points.
