Well, it is a marketing brochure, so that is pretty much expected. 
I object to the complication, ie when it fails, it will be more expensive and time consuming to fix.
But from a thermodynamics perspective, it is all very logical. Liquid coolant is far more effective at cooling than air is. If we use coolant on the engine block and head, why wouldn't we use it on other engine components and ancillaries that have high cooling requirements? Stable temperatures are better than temperature spikes, particularly for electrical components, and particularly for components that have a highly variable duty cycle. And the fact that the alternator helps warm up the passenger compartment upon cold start is a neat addition. Certainly more expensive to fix when it breaks, but then that is a common theme across many BMW engineering solutions.
