When read literally, the lower voice slur in A embraces just five semiquavers, up to g flat2, which is probably one of quite many inaccuracies to be found in that part of the manuscript. In GE (and EE) the slur embraces six semiquavers, and in FE it reaches up to the crotchet e flat2, which seems most natural in the light of slurring of analogous motifs of the upper voice. The mark added in FEJ may, but does not necessarily have to, be a slur.
