In the original version, written in AI, the bottom notes of the figuration in the R.H. double the melodic line from the middle of bar 33 – a
1-g1-g1. in A, Chopin immediately wrote the changed version, also in the L.H. where on the 4th beat in bar 33 and 1st beat in bar 34 there are two g1 instead of d1 and e1 as the top notes. Interestingly enough, the final edition of the part of the R.H. in the 2nd half of bar 33 was initially written in AI, yet it was changed there. Hence we could talk about Chopin's hesitation here. Cf. the note to bars 32-33.
