The slurs of A between b. 4 and 5 are ambiguous – the slur in b. 4, which ends the line, clearly suggests continuation, which is not confirmed by the slur in b. 5. The four-bar structure of the Prelude, emphasized by the change of register and dynamics, makes us consider the ending of the slur in b. 4 to be inaccurate, which is confirmed by the notation of both later album autographs.
