Two-Faced does not mean that the starting formation must consist
    entirely of Couples.  It simply means that somewhere in the given call
    someone will have to Replace an Arm Turn 1/2 with a Partner Trade.
    For example, from a 3 & 1 Tidal setup, on a 
Two-Faced 
    Spin Chain The Line,
    some dancers would start with a normal Arm Turn 1/2.
    Our point is that the caller can say 'Two-Faced 
anything' instead
    of 'Some Work Two-Faced, all 
anything'. 
EN: 80   Two-Faced では, 
    始めの formation が全てカップルになっている必要はありません. 
    単に, コールのどこかで, 
    誰かが Arm Turn 1/2 を Partner Trade で replace するということだけです. 
    例えば, 3 & 1 Tidal setup からの, 
Two-Faced 
    Spin Chain The Line では,
    ある人は普通の Arm Turn 1/2 で始めます.
    私達の主張は, コーラーは 
    'Some Work Two-Faced, all 
anything' でなく, 
    'Two-Faced 
anything' と言えるということです.
