One player learning from another certainly isn't unheard of. However, I would imagine that happens moreso during the course of a long season rather than a short postseason series. It depends on the situation, maybe Edmonds is more familiar with the opposing pitcher than anyone else on the roster, maybe Edmonds spots that the pitcher is tipping his pitches. Having that experience is something that could become a benefit, there's nothing negative that would come from his experience. Sure there is. Edmonds could approach ABs differently than other players. He has a different skill set and if he's trying to give advice based on what applies to his skills compared to the guy he's talking to skills he could wind up screwing with the other guy's swing/approach for no reason. On the list of the reasons Jim Edmonds is good for the Cubs postseason hopes extra hitting coach for a team full of veterans doesn't even register.
