You are correct. The SDSU player had a foot out of bounds on the simultaneous possession, if you touch the ball while out of bounds - other teams ball regardless of the tie up.
Also during the Tulane game, we got jobbed out of a point. In the second half, we have 47, and make a three pointer (announced as a three, referee raises both hands, both feet behind the line). Our score only goes to 49 on the score board. We make another three and score goes to 52. We then make one out of two free throws, goes to 53. And so on. Never corrected. Didn't effect the final outcome but if we make our desperation three, we win instead of tie and OT.
