It is difficult to say what the motivation of the reviser of GE2 was, while providing the chords at the beginning of the bar with staccato dots. Perhaps he assigned a dot over the crotchet in the cello part in Morch to the chord in the L.H., which is not entirely excluded. In any case, the sign in the R.H. is certainly absent in A.
