According to the available photograph of A, the slur over this motif starts at the beginning of b. 204. If that were true, the slur must be inaccurate, since Chopin put it over bars marked in an abridged manner, devoid of notes. From the musical point of view, such a slur could be possible; however, it seems highly unlikely that Chopin would have wanted to indicate an extremely subtle difference in phrasing in such a vague manner.
