Again, Art. 220 is titled Branch Circuit, Feeder and Service Load Calculations. The methods and numbers given are used to calculate minimum branch circuit, feeder and service sizes. Nothing is intended to indicate actual maximum overcurrent protection for a particular circuit or device. So Art. 220 has nothing to do with what you are asking. In practice, just like a circuit of receptacles, you can load a lighting track until the breaker pops. Perfectly acceptable (but not a good idea.)
Now, as pointed out, there are energy codes that try to limit the number and wattage of heads used with track lighting since they can be user installed and God forbid someone wants more light. One method is current limiting track feeds used to feed each track. Apparently also a panel for that purpose. But the problem here is that you will have to know what the current to each track (per foot) must be limited to and that will be in the energy code, NOT necessarily that given in Art 220.
BUT FIRST I would want to know if NYC even has an energy code that covers this. Like I said, I don't think this lighting designer knows what he's talking about.
