Interesting note on this whole ref situation. Thibs called for the review because he thought it didn't initially hit the line and that there would be no time remaining on the clock. He didn't do it for a free time out and in fact, believes the NBA needs to review that. He wants it changed to where players can't return to the bench during a review, thus negating any free time outs for teams that don't have any.
Also, he saw Blatt calling for the TO when he had none left, despite paying close attention to the action on the floor.
