I assume F4 had first or best shot at playing the ball.
Can't tell for sure if "both reaching for ball when R1 splits F4 and F9 and flips over both F4 and F9" means R1 contacted F4 or impeded F4 from the ball in some way. If so, then interference.
The only way I see it could be obstruction is if R1 did not contact F4 or impede F4 from the ball in some way, then F9 could be obstructing.
