IRL when you come to a complete stop on a trap, only then will you go idle. No brakes, as the ground crew signals to pull back the wire. It is a little jolt backwards, then the ground crew stops the pullback and the aircraft continues aft till the wire is released from the hook, then they signal for you to go hook up, power up to stop your aft momentum and then taxi off. Brakes aren't really used in the LA.
If you time the power to idle right (NOT right at touchdown, just really a feel thing just before you fully stop), the tension of the wire will pull you back enough to get the wire to drop off, in which case the ground crew will tell you to hook up and taxi.
If you raise your hook and the wire didn't release, they tell you to lower it again, then do the pullback, raise, thing again.
It's pretty accurate, you just don't have a cooperative ground crew helping you get clear in DCS.
