The 
asterisk is written in A clearly after the crotchet on the 4th beat of the bar, which seems to be a deliberate decision, since Chopin initially wrote it under the quaver ending the passage. In FC it is so close to the F-f octave that it seems that it is placed under it, which was reproduced as such in GE.
