The slurring of these bars in A is not entirely clear due to the transition to the new line of the text. However, it does not seem that Chopin would like to deviate from the clear slurs he wrote in AI. This is how it was most probably understood in the base texts for FE and EE, as well as CDP. The two-bar slur in GE is a different attempt to interpret the notation of A, yet it does not reveal anything concerning Chopin's view on this issue.
