Backcourt Violation called (Video) - Was this the right call?

[Nevadaref]

Not a backcourt violation due to the throw-in exception part of the rule, even though the player lands first with his right foot in the frontcourt and then his left foot in the backcourt. However, he then takes another full step with his right foot without dribbling, which is a traveling violation.

The only way that this would be a backcourt violation under current NFHS rules is if the defender guarding the thrower tipped the pass. That would eliminate the throw-in exception for the offensive player catching the ball. It does not look like that is the case in the video.
