Depending on the buddy and the location, My buddies and me usually switch leaders. We do the usual pre-dive planning and know the dive profile , but I may start leading and then he'll lead awhile and we go back and forth. We just kinda know if your in front you keep track of your buddy behind.
The dives I'm talking about are stomping grounds dives ... I'm not talking about new dive sites.
