I worked at Sik and was a rotorcraft engineer for 8 years, master's concentration in fluid mechanics. A stopped rotor with active flow control is a world and era apart from slowed rotor configurations. Almost none of the engineering overlaps, they're completely different approaches except for an end goal of wanting faster forward flight. Similar vs different is semantic at this point. It's like saying the bicycle gave rise to the hovercraft, which is true in a sense.
