Double Clutch..

[yaba]

I know that double clutching id preformed, to lower the impect on the gear box/ the clutch.

Some people told me that in synchronized cars, you don't have to release the clutch, when you move your gear to nutral.
If i understand correctly, the synchronizing is happening in the gear box.
When I release the clutch in Nutral, I connect the FlyWheel to the engine and accelerate them both, with the Gas.
How does the synchronization connected to all of this??
Why don't i have to release the clutch in nutral anymore?
