If the ballast was a constant current source then that resource would make sense to me. You can make a power supply that forces the current at a steady rate. But a simple inductive ballast isn't that.
But if you re-read the resource you quoted, he stated that he did NOT try it.
I can't see a HID puling current differently form everything else. I work with DC excited plasma discharge, and its still the same. We adjust the amount of available current (through vacuum tubes) and use the gas mix to adjust the differential of the voltage drop. (which stabilizes the power dissipation of the tubes)
