According to the notation of AsI, the intended shape of the melody of this fragment always included the bottom second (b1), both in the introduction and the ending. Therefore, the fact that A (→GE1→EE) does not include a written-out ending of the trill does not mean that Chopin intended a performance without an ending; it is simply an inaccurate notation. The changes introduced into GE2 and FE resulted from Chopin's intervention, whereas GE2 misinterpreted Chopin's indication, as a result of which the grace notes were encompassed with an octave sign and not added after the trill (as they should be).
