The indication of A may be considered to be an abbreviation or to be even unfinished – Morch includes Cor de Signal (written by the copyist's hand) in this place. The extended indication in GE1 (→FE→EE, →GE2) is probably a result of proofreading, possibly Chopinesque – the dot after 'Cor' suggests that the word was initially an entire indication, in accordance with A.
