Another strange bug with D4, possibly D800!?!?

Could anyone verify this with your D4 please?

1. Focus using the shutter half pressed (both AF-C and AF-S show the error) and hold the AF-ON button configured to "AF lock only" using a8 to freeze the focus.

2. Recompose to totally different lightning, still hold AF-ON, exposure changes in viewfinder, but not to the "right exposure". A shoot would be misexposed.

3. After recompose, let the AF-ON go. Does the exposure in viewfinder change dramatically now? That´s what mustn´t happen. The exposure would be right now, but it must have been without letting the AF-ON button go. Letting the AF-ON button go makes you lose the focussing.

I found that D800 doesn´t have this option for the AF-ON button, so this seems to be a D4 only error if it also happens with your cam. Could you check this please?
