EE and GC (→GE) have the 
mark placed under the last chord, while FE has it placed after that chord. It is difficult to guess without the autograph what Chopin's authentic notation was like, and anyway even that notation could have been ambiguous. For our main text we adopt the version of the two out of three sources probably based on the autograph, i.e. EE and GC. A similar situation occurs in the analogous bar 460.
