I think it makes sense when you read it carefully. What tripped me up is that quiescent current is usually only seen as a bad thing. It not drawing enough current also seems more like a symptom than the cause.

On my first pass I was also a bit confused whether he is talking about the regulator's internal circuitry or something else: It's not obvious that LDO stands for low-dropout regulator, so at first it felt like he's misusing "quiescent current" to refer to some kind of "standby current" (comparable to an ATX power supply +5V Standby line) that the regulator has to supply to some other circuitry that then powers on the regulator to supply the rest of the device.
