Frontcourt status question for FIBA officials

[Jay R]

The question below was a case question that I found for FIBA rules. When I first read it, I thought the answer was No because it would be a BC violation. Turns out the answer is Yes. Am I the only one who thinks that FIBA is not consistent here. If A3 had jumped from the FC and caught the ball in the air and landed in the BC, it would have been a BC violation. Yet this play is legal.
Comments?

Team A has the ball for a throw-in at the centre line following an unsportsmanlike foul. Player A3 receives the in-bounds pass with his left foot on the floor completely in the frontcourt and his right foot off the floor.
A3 then puts his right foot down on the floor in the backcourt. Shall the official start an 8-second count?
