It was written poorly but the only risk I see to a NSS is if the price rises, which is unlikely as the short seller is pushing the price down. The person selling my franchise without my permission is likely to end up in the big muddy si he/she/it is in a high risk situation.
Now what is your explanation for the risk to the person shorting.

The risk to the shorter is unlimited risk. A stock can only go to zero but can go up infinitely.
