The shorter slur in Atut (→FE→GE1→GE2) is the original marking. Initially, both slurs in the previous figure also encompassed the groups of three quavers only; however, they were then prolonged by Chopin. The slur in the L.H. in the discussed bars, written last, already encompasses the entire four-note motif. The fact of leaving the slur in the R.H. without extension must be the composer's inadvertence.
