The A slur in the 1st half of the bar is written under the top voice quavers; when interpreted literally, it seems that it starts from the second one (c
2) or from the g1 minim. It must be Chopin's inaccuracy – cf. numerous appearances of this motif, e.g. in the 2nd half of the bar – hence we interpret it as a half-bar slur concerning the top voice. This is how this slur was interpreted by GE; however, it was mistakenly reproduced there twice – over the quavers and almost horizontally under the quavers, which makes it resemble a tie to g1. In the remaining editions both slurs were repeated, but it was assumed that the bottom slur/tie refers to the bottom voice minims, which resulted in two completely arbitrary versions – with a slur concerning g1-f1 in FE and IE and with a tie to g1 in EE.
