Landing with broken rudder cable

Please check it and correct me if I'm wrong.

Usually the only springs in the rudder lines are those in front of pedals. Those springs keep the whole rudder line in tension.

What happen if let's say the right rudder cable breaks: right pedal goes full forward and the same do the left pedal. The glider start circling left. Possible correction: pull the pedals rack all the way back and put the left foot heel over the left pedal and pull back.
