Over 5000 FUE grafts in a single session and this man now is balding in the back of his head

More than 5000 grafts performed in this limited space with FUE will deplete the donor area and this many will now have this huge discrepency between his donor area that was not harvested and the area that was harvested.  Ther are two solutions for this type of balding (1) is  scalp micropigmentation (https://scalpmicropigmentation.com/scar-covering/) and the second might be just to grow the hair he has long enough to cover the donor area. The over-harvested FUE means that he can never keep his hair short unless he has scalp micropigmentation.
