Assumptions based on bar type sure are foggy. Drop bars can be mounted on almost anything and not limiting of shifters, thumbs have been mounted up on the flats and Genevalle puts them on brake levers.
I suspect IRD's differentiation is about bottom bracket width and "drop bar" being equated to 68mm "road" BB standard. Some road FDs just don't have the outward throw to go to the big ring and the extra 5 mm that 73mm BBs require. It's an odd thing for a maker/marketer of them to be discrete about, or not know outright when you ask them to differentiate.
