The version of the 2nd half of the bar added in AsI seems to be the first version of the final text, hence we regard it as a variant of the latter. However, as upon the return of this bar (bar 19) AsI has only one version, identical to the final one, all three versions can be actually treated interchangeably.
The AsI notation is inaccurate in terms of accidentals – in the principal version the 
raising e
2 to e2 is written only just in the 4th R.H. figure, while in the added version there is no natural at all. On the other hand, in the L.H. part, Chopin unnecessarily repeated a to e1 in the 4th passage.
