As I continue to edit the Chopin Etudes, more interesting examples occur which I will share as time allows. Here is a spot from the Etude op. 10 no 6. Chopin suddenly changes stem direction to show that 16th-notes 7-12 in measure 2 pick up from the previous bass note E

as a bass voice imitating tenor voice 16th-notes 1-6 rather than merely continuing them. They then lead to the bass note in the next measure, which is also notated with a down stem.

This beautiful notation appears in none of the first editions or any successive edition known to me. The editors all "correct' it according to standard engraving practice. Here is the French first edition:
