Take an extreme example. Light plane and 100 kt headwind. You get airborne at 120 IAS with 20 GS. Reach 50 ft and then abort. Then land immediately at 120 IAS GS 20. You could clearly blast away on your reversers to full reverse until the IAS reaches 60 before you would have a problem.
Not sure if that makes sense.
it is not approved to reverse the A/C (negative GS) with reverser use.
