I wonder if the engine cutoff is done manually or what kind of sensors turn it off. I would think maybe some sort of pressure sensor on those stability arms or something would indicate the rockets actually on the pad before turning off the engines maybe. Perhaps some sort of back draft would trigger that though if it's too sensitive or the threshold is too low. Or maybe sensors built into the landing pad itself that signal to the rocket.
Not sure about Nebula-1, but I'm pretty sure Falcon 9 uses radar for judging the distance on final descent.
