In reply to Joffy:
As you say, and as mentioned in the link, it's not possible to tension the previous institu wire sufficiently meaning that in the event of a failure, the wire and the second bolt would be shock loaded. We looked at alternative methods for an institu connection but for the time being, climbers must rig their own setup to equalise the load on the bolts.
This was driven by a ongoing programme of maintenance and review. All the Best
