Looking at the notation of the L.H. in A, one can see that the 
sign is written under a
1, the 1st note of the triplet on the 2nd beat of the bar, whereas the 
sign under g1, the 2nd note. According to us, Chopin was writing pedal change while looking at the R.H., since the change is undoubtedly related to the appearance of a new trilled note. Due to this reason, we interpret the pedalling of A in the main text in this way.
