Karate teacher did this hand gesture- karate chop in the crook of the elbow with other arm pointing up is this a karate gesture?

my nephew is 9 years old his karate teacher did this hand gesture After walking my nephew to the car for pick up at my sister. I know what I think it means but before telling her I want to make sure it's not some kind of karate move.


Its a traditional informal form of salute and recognition among some types of martial arts.
