This paragraph in the EX(1) Finish Manual says I should keep inspection hole cutouts in a safe place. Wondering why?

SECTION 53 INSPECTION HOLES

Before we install the jury struts, it is prudent to cut the inspection holes in the bottom of the wings.
There are 3 holes on the right hand wing and 4 holes in the left hand wing. Try to cut the holes so that you remove a circular piece of material. Put the material that is removed into a zip lock bag and store it in a safe place. See the photographs.
