Lack of d1 in the 3rd chord in bar 48 in A and deletion of this note in bar 49 prove Chopin's hesitation, as, eventually, he added the note in both bars, while proofreading FE (→GE,EE). Admittedly, the composer had to choose between the correct voice leading and a more graceful and fuller, as far as the sound is concerned, pianistic grip.
