Can you leave a hair or two behind with an FUE?

Hi doc I had a quick question. If a 3-4 hair follicle is grafted with FUE, can one of the hairs be sliced off and inserted back into the donor site? You get a 2-3 hair follicle to use on the head and the single hair follicle growing out of the donor site would make scarring irrelevant.

Sometimes the surgeon will see a 4-5 hair graft, leave 2 hair or two behind as only 3 hairs may come out. Sometimes the follicular units are not tightly bonded and one or two of the hairs in a 5 hair follicular group can be seen exiting in a wider splay.  The punch size often limits the number of hairs per follicular unit that is removed and when there is splay, it is not unusual to take out just the closely bunched hairs. The hairs that remain, will grow.
