According to us, an earlier placement of the 
hairpin in GE than in A is a result of carelessness of the engraver of GE1. Reversing the direction of the sign in FE (→EE) is probably a mistake too, however, in this case the sound result can be considered to be at least equal with respect to the original notation of A. In the main text we leave the undoubtedly authentic sign of A, yet the version of FE can be considered a fully-fledged performance variant.
