The difference between a brand and comms planner

According to Julian Cole's slideshare, there are two types of planners out there involved in the creative process.

It seems like they are quite different when it comes to skill sets and the way they look at it. Right now the presence of the comms planner is very dispersed - you would more likely find them in media agencies or as digital-only strategists. My question is, should we be concerned, or can the brand planner be that jack of all trades?
