FIBA Rule Interpretation

[Teigan]

So with us Canadians going to FIBA this year, I've started studying a little early, and I've hit a stump.

Rule 4
Article 8.8 & 8.9

8.8
If a foul is committed when or just before the game clock signla sounds for the end of playing time, any eventual free throw(s) shall be taken after the end of playing time.

8.9
"If an extra period is required as a a result of this free throw(s) then all fouls that are committed after the end of playing time shall be considered to have occurred during an interval of play and the free throw(s) shall be administered before the beginning of the extra period."

I understand 8.8, but 8.9 confuses me.

I've tried to create a scenario to help me explain this to myself.....

While the horn is going A1 fouled B1 with the score @ 68-70, and if B1 scored both free throws making the score 70-70.(So were going to overtime right??)
But while B1 is shooting, A2 fouls B3, and now B3 is shooting. If B3 only makes one shot and the score is 71-70....are we still going to overtime????

Anyone want to help me?
