In FE, similar motifs in these bars are provided with different slurs, which is a good reason to suspect an inaccuracy. Respective unifying revisions were introduced in EE and GE3. According to us, each of those versions may correspond to Chopin's intention. In the main text, however, we leave the varying slurs, since Chopin used to provide similar motifs with different slurs – cf. e.g. bars 45-47 and 111-114. Considering the entire four-bar section in bars 466-469, we observe that the varied slurs can be considered to be harmonising with the progressive crescendo – in bars 465-466 and 466-467, the slurs end on the first octave of the bar, whereas in bars 468 and 469, the first octave is not encompassed with a slur, which somehow enhances articulation (in bar 469, there is also marcato).
