Most games with replay functionality do not save everything that has happened. Rather they save the seed of the RNG and every input command for every frame. For the replay to match the original playthrough the game needs to calculate exactly the same values it did before. So every difference between PCSX2 and the real PS2 can really messes things up.
Cars are 0.0001% faster? After one lap this accumulates and the input does not match anymore. Collision detection is slightly off? In the replay the car might not be able to barely avoid get the corner and crashes.
So this replays won't match until PCSX2 emulates everything very very exactly. Even with all the extra clamping, all speedhacks turned off, there are many things a tiny bit off.
