Defending the tren lock means defending the knee, not the foot. The attack builds a V around the knee by reaping a leg over the trapped leg and locking behind the shin, then closes a triangle to hold the shape. The Achilles finish arrives afterwards, against a leg that can no longer rotate.
That order decides the whole defence. Every escape worth drilling happens before the triangle closes. After it, the defender is fighting an ankle lock without the rotation that normally defends one.
