In FED, there is a diagonal line written in pencil under the entire passage (from d1 to a2). Chopin would use more or less diagonal lines to, e.g. mark synchronisation of ornaments (cf. bar 403); however, in this case it does not indicate a specific note both in the left and right hand. Moreover, it does not seem to be a mark emphasising the meaning of the rest, like it is in bar . Therefore, it might have been a mark accompanying a verbal indication concerning smooth performance of the passage.
