When the payload sees a master update with a leader, then update the leader master segment cache with the leader instead of resetting the leader cache. Thats because its possible with split brain that we still have 2 actives bound on tipc logical address and hence a masteraddressget through tipc or transport topology service would end up calling out to the wrong master (actual deputy but pending restart or deputy update on a link merge). The end result would be the payload services wouldn't be started if the registration ends going to the last active or actual pending deputy and it would be just transitioned to boot level 5 by the last active without service start after a split brain merge
