No d1-g1 fourth on the 4th beat of the bar is most probably a mistake (the dyad was either overlooked or left out due to an erroneous placement); in GE1 it was placed in such a way that on the upper stave the bar seems to have five crotchets.
In the main text we adhere to the notation of A, omitting only the unnecessary in this context cautionary before g1.
