True but I doubt someone serious about networking is going to be confused about this. The CPU in a switch is just for config and management. MT is flexible in that you can do some routing with the switch CPU but that doesn't mean you should.
I've seen plenty of people getting tripped up by this, sometimes quite publicly (like the blogger who returned the Mikrotik switch they got for their 25Gb/s home internet connection because turning on NAT turned it into a noisy space heater...)
