I may be wrong but I think Jay Sata's point was that if Ewald Gritsch was just "her passenger" in the Stearman, as TCT claims, he would not need an FAA licence.
Perhaps he wanted in case he had an urge to do some local solo flying/aerial sightseeing while the intrepid aviatrix and adventurer took the occasional hard earned break from her epic journey across America.
Or in case he wanted to do some air tests following engineering work.
Or just as a souvenir of the momentous flight in which he was privileged to a passenger.
There could be a whole host of reasons why he wanted an FAA licence even though he wasn't sharing the flying, just a passenger.
Jay can be so unkind at times.
