Cable ladder bonding

Saw this recently on site, there is a bond across every cable ladder joint. I do not believe that this is necessary as this is not an exposed-conductive-part or an extraneous-conductive-part. Am I right?

    Depends on the situation - for example if it's an environment for telecoms or IT equipment it might be required under BS EN 50310 - where additional bonding to form a mesh or grid might be needed for EMI or functional reasons rather than just shock protection.
