When interpreted literally, the 
sign in A (→GE1→FE) suggests pressing pedal on the 5th, 6th or even 7th quaver in the bar. According to us, it is an inaccurate notation – Chopin had already little space under the note and writing the sign before would be even more misleading. According to us, it is EE that interpreted the composer's intention correctly.
In all copies of GE1a, the discussed sign was overlooked as a result of an inaccurately performed graphic proofreading of bars 235-236.
