The 
mark's placement in FE seems to be inaccurate, as depressing pedal already after the passage had started is unjustified from the point of view of the sound. Therefore, there must have been a misunderstanding in the interpretation of Chopin's notation. Both in GE1 (→GE2) and EE was moved slightly to the left, under the quaver rest, which may be considered as an acceptable interpretation of this mark. However, most probably the pedal is to be depressed already at the beginning of the bar, as it was marked in GE3 (→GE4→GE5).
