The missing in GE could be explained by the possibility that the mark was added in the last proofreading of FE; however, the additional absence of the slur in the L.H. in this bar makes a possible inadvertence of the engraver of GE more likely; the engraver overlooked a certain stage of work here – the elements between the staves, unrelated to the particular notes. See also bar 394.
