The chin is not 'tucked' behind the left shoulder except in an extreme defensive position. 'Tucking' the chin into the left shoulder turns the neck into an unnatural position, takes away the support of the muscles, and prevents straight bone alignment. It also tenses the left shoulder and arm, preventing free action and causing fatigue.
