In FE (→EE), the placement of the 
marks suggests that the first one concerns the R.H., whereas the second one, the L.H. Since it does not seem likely that such differentiation could be intended by Chopin in this context, both marks are probably misplaced. In the main text, we move them to between the staves, since, according to us, they refer to both hands. Changes striving in that direction were gradually introduced in GE1 (→GE2) and GE3. See also the adjacent note.
