when to shoot?

[jeremy341a]

If a technical foul occurs after the ball has become dead to end a quarter, the next quarter is started by administering the free throws. This applies even when the foul occurs after the first half has ended. It also applies when the foul occurs after the second half has ended, provided the score is tied. If the score is not tied, the free throws are administered unless the outcome of the game will not be affected. If the outcome is not already decided, the free throws are attempted immediately as if the foul had been a part of the fourth quarter. In this case, if any overtime period is necessary, it will start with a jump ball. The division line throw-in following the technical foul cannot be carried over
to the overtime as the fourth quarter ended with the last free throw. (R5-S6-A4)


Am I reading the casebook correctly when I read if they score is tied then you don't shoot the freethrows until the overtime period but if the score isn't tied then you shoot the freethrows right then, assuming it can change the outcome of the game.

So if B1 receives a techinical after the ball is dead and the score is tied then A doesn't get to shoot until the start of the overtime and therefore can not win in regulation.

However if the score is not tied say team A is down by a point then they do get to shoot the freethrows and possibly win in regulation?

Is this true or am I reading this wrong?
