It might be worth getting a 'formal' interpretation. After all, the coffee maker we're discussing is most certainly a counter-top appliance. I note that the 'exceptions' to the 'no other outlet' rule are both items that are not appliances that you might set on the counter.
You're citing 210.52 B 2. Perhaps we're better served by 210.50 C, which provides that receptacles intended for specific appliances be mounted near that appliance. It's a bit of a stretch, but since they illustrate their point using laundry equipment as an example, perhaps we might infer that they assume that a receptacle for a specific appliance would have it's own dedicated circuit.
We also have 210.21 B 2, which addresses the maximum cord-connected load for a circuit. If that coffeemaker gobbles up all the power, you can't really add more receptacles to the line, can you? (Be wary of this one, though ... think of all thos microwaves, toaster ovens, and bread machines!)
Looking at 210.11 C 1 (where the two SABC requirement is), it occurs to me that a 240v circuit, supplying a 240v receptacle, is but ONE branch circuit. Split off 120 'legs' all you want, it's still ONE circuit. With the 240v receptacle, we can't call it a 'multi-wire branch circuit.' I think that's the section we need to cite.
