Why is a bond bushing required? Don't know the full scope of what we are looking at by the closeup pic?

It is a service enclosure with a metal raceway through an intact KO. The picture is not clear but one of the knockouts is left in place.

250.92(B)
Method of Bonding at the Service. Bonding jumpers meeting the requirements of this article shall be used around impaired connections, such as reducing washers or oversized, concentric, or eccentric knockouts. Standard locknuts or bushings shall not be the only means for the bonding required by this section but shall be permitted to be installed to make a mechanical connection of the raceway(s).

Isn't that a bonding screw that's bent and not being used? and a regular lock nut on the other?
