The crossings-out visible in A allow us to read the original version, in which the L.H. had the same chords as the R.H., continuing the relationship marked by the 1st chord of the entire passage. Chopin wrote four subsequent chords (to the second one in bar 482) before he changed the concept or noticed his mistake.
