One can ponder whether the difference in pedalling between bars 45-46 and 61-62 was intended (deliberate) by Chopin and whether it is not a mere difference in the notation, as it sometimes happen in similar contexts. A clear differentiation of performance indications between bars 33-48 and 49-64 (other dynamics and slurring) demonstrates that it is an intentional difference, indicating varied approach to the pedalling in these pairs of bars. The revisers of later GE and EE had a different opinion, as they changed the pedalling of bars 61-62 after bars 45-46. Similarly in bars 125-126 and 189-190.
