I missed this before, and it's not true. This is correct for the 850, which uses a V12 that is essentially as you describe - two engine computers, intakes, throttle bodies, fuel pumps, etc. One for each bank of 6 cylinders.
But the 94-95 840 uses a much simpler 4.0L V8 motor that is much more standard in terms of how it operates and - aside from the problems they had with the Nikasil blocks early on - has proven to be a very reliable motor, as long as it is maintained properly. The same motor was used in many 5 and 7 series models as well. Actually, that's a major reason I opted for an 840 over an 850 when I bought the car.
I would say the reliability is about the same. You can go on Ebay all day long and find cars using the M60 V8 with 150+K miles on them and running great.
Here's a 1993 740ilwith 214k on it
